MailerLite vs GroupPost
If you're comparing MailerLite vs GroupPost, you're probably a community organization — an HOA, a faith group, a club, a nonprofit — that has outgrown BCC sends and is trying to figure out which tool to use next, or a current MailerLite user wondering why your open rates aren't as high as your membership engagement suggests they should be. MailerLite is genuinely excellent email marketing software. GroupPost is community group email. They solve different problems, and the distinction matters — because if your members already know you and want to hear from you, the fastest path to higher open rates isn't better subject lines. It's getting your messages into the primary inbox instead of the Promotions tab. This comparison explains exactly what each tool is designed to do, where each one wins, and the one question that tells you immediately which one you need.
TL;DR — Which one is right for you?
- Choose MailerLite if you are growing a subscriber list to drive conversions: donations, product sales, or newsletter readership. You need drag-and-drop templates, multi-step automation, A/B testing, and a conversion analytics funnel.
- Choose GroupPost if you are running a community — a nonprofit, HOA, faith group, club, or school organization — where members already know you and need to hear from you reliably. GroupPost delivers to the primary inbox, not the Promotions tab, and pricing scales with how much you send, not how many members you have.
- The single deciding question: Are you trying to grow an audience, or communicate with one you already have? MailerLite grows audiences. GroupPost serves them.
- MailerLite's free plan was cut from 1,000 to 500 subscribers in September 2025. Growing organizations hit the paid tier sooner than before.
- GroupPost's free plan covers 100 messages per month — every feature included, no subscriber count ceiling, no credit card required. Enough to run a real send to your list and see delivery and open tracking in action before you spend anything.
What Each Tool Actually Does
The most important thing to understand before comparing MailerLite and GroupPost is that they are not competing products. They occupy different categories, serve different use cases, and are optimized for different outcomes. Comparing them on a features-per-dollar basis misses the point entirely.
MailerLite: email marketing platform
MailerLite is an email marketing platform. It is designed to help you grow a subscriber list, nurture that list with campaigns and automated sequences, and drive conversions — donations, sign-ups, purchases, or any other measurable action. Its core strengths are its drag-and-drop template editor, automation builder, landing pages, A/B testing, and campaign analytics. It is built for the sender who wants to measure results and optimize over time. The relationship it models is brand-to-audience: a professional organization sending polished content to people who have opted in to hear from it.
GroupPost: community group email
GroupPost is community group email built for organizations where the members are the community — HOAs, faith groups, clubs, school PTAs, sports leagues, nonprofits, neighborhood associations — and where the communication goal is to keep members informed reliably, not to convert them. Its core strengths are authenticated group sending (SPF, DKIM, DMARC via AWS SES), primary inbox delivery rather than Promotions tab routing, reply routing that goes to the sender rather than the whole list, multiple group lists without per-contact pricing, scheduled and recurring sends, and automatic bounce management that requires no manual list hygiene. It includes a full rich-text message editor with image uploads, tables, formatted links, and reusable message templates — alongside open and delivery analytics so you can see exactly how well your community is engaging.
The relationship it models is organization-to-member: a community communicating with people who already belong to it and want to hear from it. That pre-existing relationship — combined with primary inbox delivery — is why GroupPost users consistently see open rates that outperform what the same list would achieve through a marketing platform. When your announcement arrives in the primary inbox instead of Promotions, more members see it, more members open it, and more members act on it. No A/B testing required.
The simplest possible summary
MailerLite is the right tool when your email goal is marketing — growing, nurturing, and converting an audience. GroupPost is the right tool when your email goal is communication — reaching the members of a community you already have, reliably, with open rates that reflect genuine engagement rather than subject line optimization. If your members already want to hear from you, the fastest path to better open rates is getting your messages into the primary inbox — not running A/B tests on the Promotions tab.

Pricing Compared
Pricing is where the category difference between MailerLite and GroupPost becomes most concrete — because they charge for fundamentally different things.
MailerLite pricing (as of March 2026)
MailerLite's pricing is per-contact. As your subscriber list grows, your monthly cost increases regardless of how often you send. Key changes in 2023–2025:
- Free plan: 500 subscribers, 12,000 emails/month. MailerLite branding on all emails. No newsletter templates. No priority support. In September 2025, MailerLite halved the free subscriber limit from 1,000 to 500, migrating all existing free accounts to the new ceiling.
- Growing Business plan: From $10/month for 500 subscribers with unlimited emails. Price scales with contact count — 1,000 contacts costs more, 2,500 contacts costs more again.
- Advanced plan: From $20/month for 500 subscribers. Adds multi-trigger automations, custom HTML editor, promotion pop-ups, unlimited user seats.
- Nonprofit discount: 30% off all paid plans. Requires application and approval. Cannot be combined with the annual billing discount (10%).
The free-plan cut follows a broader industry pattern: Mailchimp's free tier was reduced from 2,000 to 500 to 250 subscribers between 2022 and 2024, and removed free automation entirely in June 2025. MailerSend cut its free tier from 3,000 to 500 monthly emails in the same period. Free plans across email marketing platforms are reliably shrinking over time.
GroupPost pricing
GroupPost's pricing is per-message sent, not per contact stored. Your community can grow to any size without triggering a pricing tier change — the cost reflects how often you communicate, not how many members you have.
- Free plan: 100 messages per month. Every feature included. No GroupPost branding. No credit card required. No subscriber limit. Sized to let you run a real send to your actual list and see exactly how delivery, open tracking, and bounce handling work — before you commit to anything.
- Starter — $5/month: Up to 1,000 messages per month. All features. No subscriber ceiling. Suits small clubs, committees, and neighborhood groups that communicate frequently.
- Pro — $9/month: Up to 5,000 messages per month. The right tier for growing nonprofits, faith communities, and active HOAs that send to larger lists or send more often.
- Team — $29/month: Up to 30,000 messages per month, with up to 5 team members. Built for organizations running multiple lists with shared admin responsibilities.
- Enterprise: Custom pricing, dedicated SMTP, white-label, role permissions, and a dedicated account manager for large organizations with high-volume needs.
At every tier, the member count has no pricing impact. A community that grows from 200 members to 2,000 members pays the same rate as long as its sending volume stays within the plan — community growth is rewarded, not taxed.
The practical implication for community organizations: a faith group that grows from 200 members to 800 members over two years pays progressively more on MailerLite at every tier boundary. On GroupPost, the same growth has no pricing impact as long as message volume stays within the plan. Community growth is rewarded, not taxed.
The Promotions Tab Problem — and Why It Matters More Than A/B Testing
This is the difference that matters most for community organizations and receives the least attention in tool comparisons.
Many community organizations using MailerLite try to improve their open rates through A/B testing subject lines, tweaking send times, or experimenting with preview text. These are legitimate techniques — but they are optimizing the wrong variable. If your messages are landing in the Promotions tab, you are competing for attention against retail newsletters, discount codes, and subscription confirmations. The ceiling on your open rate is set by where the message lands, not by how compelling the subject line is.
Gmail (and increasingly Outlook and other clients) routes emails to tabs based on signals in the message itself. Marketing emails — characterized by HTML templates, tracked links, unsubscribe footers, and sending-platform headers — are classified as promotional content and routed to the Promotions tab. This is not spam. It is not a deliverability failure. It is Gmail correctly identifying that the message looks like marketing.
The problem for community organizations is that their announcements don't look like marketing to the sender — but they look exactly like marketing to Gmail's classifier, because they are sent from a marketing email platform. The result: a neighborhood association's emergency water shutoff notice, a church's Sunday service reminder, or an HOA's annual meeting announcement all land in the Promotions tab alongside newsletters from e-commerce brands.
MailerLite acknowledges this directly: as an email service provider, it has no ability to control where emails land — Gmail's algorithm makes that determination based on content and sender signals. Paid plans let you remove the MailerLite branding, which helps slightly, but the underlying template format and sending infrastructure still look like a marketing platform to Gmail's filters.
GroupPost sends through authenticated plain email infrastructure (AWS SES with SPF, DKIM, DMARC configured) in a format that looks like email from a real person or organization — not from a marketing platform. Gmail routes these messages to the primary inbox. For community organizations with engaged, willing audiences, the difference between a primary inbox arrival and a Promotions tab arrival can be 30–40 percentage points of open rate on the same list. The members haven't changed. The subject line hasn't changed. The inbox has.
If you are a nonprofit, club, or community group that already has a good relationship with your members — people who want to hear from you — the single highest-impact change you can make to your open rates is moving your messages out of the Promotions tab and into the primary inbox. GroupPost does that by design.

Who Wins Each Scenario
| Your situation | Best tool | Why |
|---|---|---|
| Nonprofit sending monthly newsletters to grow donor base, with donation CTAs and open rate tracking | MailerLite | You need templates, A/B testing, conversion tracking, and automation. The marketing platform features are essential to what you're doing. |
| HOA board sending announcements, meeting reminders, and community updates to 150 homeowners | GroupPost | You need inbox delivery, reply routing, and no per-contact pricing. You are not marketing — you are communicating with your community. |
| Church sending a weekly bulletin to 400 members | GroupPost | Members expect the bulletin in their primary inbox, not in Promotions alongside retail offers. Per-contact pricing penalizes growth. GroupPost is the right category. |
| Nonprofit that needs both: a donor newsletter AND operational updates to volunteers | Both | Use MailerLite for the donor newsletter (conversion-focused). Use GroupPost for internal operations and volunteer coordination (communication-focused). |
| Sports league coordinator sending schedule updates and game cancellations to 80 players and parents | GroupPost | Urgent operational messages need to arrive in the inbox immediately. No templates needed. No subscriber count ceiling. |
| Small business sending promotional emails to a customer list | MailerLite | You are doing email marketing. MailerLite is designed for this. GroupPost is not the right tool for commercial promotional campaigns. |
| Community organization on MailerLite's free plan, approaching 500 subscribers and needing to decide whether to pay | GroupPost | If your emails are community announcements rather than marketing, you're paying for marketing features you don't use — and getting inbox placement you don't need. GroupPost's free plan covers the use case with no subscriber ceiling. |
| Nonprofit or club already on MailerLite paid plan with a highly engaged list, but open rates are lower than expected | GroupPost | If your members want to hear from you but opens are disappointing, the Promotions tab is the likely cause — not your subject lines. Moving to GroupPost changes where the message lands, not what it says. Primary inbox delivery typically closes the gap faster than A/B testing does. |
| Organization that sends surveys, RSVPs, or intake forms to its members | GroupPost | GroupPost lets you embed form links directly inside the message body, with responses tracked back to the message — no separate platform needed for member surveys or event RSVPs. |
When It Makes Sense to Switch
The most common situation where community organizations move from MailerLite to GroupPost is hitting the free-plan subscriber ceiling. With MailerLite's September 2025 reduction from 1,000 to 500 free subscribers, organizations that were comfortably on the free plan now face a choice: pay for a tool optimized for marketing, or move to a tool designed for what they're actually doing.
But the more compelling case isn't about price — it's about open rates. If your organization has a genuinely engaged list, members who joined because they want to hear from you, then you are almost certainly leaving open rate on the table by sending through a marketing platform. Switching to GroupPost doesn't change your list or your content. It changes where your messages arrive. For organizations that already have the relationship, that's the highest-leverage move available.
The migration signals that indicate GroupPost is the better fit:
- Your open rates are lower than expected and you suspect the Promotions tab is the cause — not subject lines or send frequency. If your members opted in and know you, the inbox is the variable to fix, not the copy.
- Members are complaining that they missed announcements because they didn't check Promotions.
- You're not using the marketing features — no A/B tests, no automation sequences, no conversion goals. You're paying for tools you don't need.
- Your list is growing and you're approaching or crossing a MailerLite pricing tier, increasing your monthly cost without a corresponding change in what you're doing with the tool.
- You send on a regular schedule — weekly bulletins, monthly newsletters, biweekly updates — and want that handled automatically with recurring sends rather than manually each time.
- You want to add RSVP tracking or member surveys alongside your group messaging, without managing a separate platform.
Moving a member list from MailerLite to GroupPost is straightforward: export your subscriber list from MailerLite as a CSV and import it into GroupPost. Members who were already subscribed don't need to re-confirm; your first send from GroupPost will reach them in their primary inbox.
Ready to see what your open rates look like from the primary inbox?
GroupPost is free for up to 100 messages per month — every feature included, no subscriber count ceiling, no platform branding. Paid plans start at $5/month. If your community already wants to hear from you, GroupPost gets your messages in front of them. Start your first group list in under two minutes.
Frequently Asked Questions
Is MailerLite better than GroupPost?
Neither tool is universally better — they serve different purposes. MailerLite is better when your goal is email marketing: growing a subscriber list, running campaigns with conversion goals, A/B testing subject lines, and measuring ROI. GroupPost is better when your goal is community communication: reaching the members of an organization you already have, with inbox delivery rather than Promotions tab routing, and without paying per contact as your community grows. If you are a community organization — HOA, faith group, club, nonprofit — sending operational announcements rather than marketing campaigns, GroupPost is the more appropriate tool for your use case.
What happened to MailerLite's free plan in 2025?
Starting September 23, 2025, MailerLite reduced the subscriber limit on its free plan from 1,000 to 500. Accounts that had between 500 and 1,000 subscribers had their sending stopped automatically — campaigns, automations, and manual contact additions were disabled until the account either reduced its list below 500 or upgraded to a paid plan. The email send limit of 12,000 per month remained unchanged. This follows a broader industry trend: Mailchimp cut its free tier from 2,000 to 500 to 250 subscribers over the same period and removed free automation entirely in June 2025. Free plans across email marketing platforms are consistently being reduced over time.
Does MailerLite put emails in the Promotions tab?
MailerLite itself acknowledges that it cannot control where Gmail routes messages. Gmail's algorithm classifies email based on signals including HTML template format, tracked links, unsubscribe footers, and the sending platform's headers — all of which are present in a typical MailerLite campaign. As a result, emails sent from marketing platforms including MailerLite frequently land in Gmail's Promotions tab rather than the Primary inbox. For community organizations whose messages are operational rather than promotional, this creates a real problem: announcements that members need to see are routed alongside retail newsletters. GroupPost sends via authenticated plain email infrastructure that Gmail routes to the primary inbox because it doesn't exhibit marketing platform signals.
Can I use both MailerLite and GroupPost at the same time?
Yes, and for some organizations this is the right answer. A nonprofit might use MailerLite to run its donor newsletter — with templates, A/B testing, and conversion tracking — while using GroupPost for volunteer coordination, board announcements, and operational communications where inbox placement and reply routing matter more than marketing analytics. The tools don't compete on your account; they serve different email functions within the same organization.
How does GroupPost pricing compare to MailerLite for a growing community?
MailerLite charges per contact — as your subscriber list grows, your monthly cost increases at each pricing tier regardless of how often you send. GroupPost charges per message sent, not per contact stored. A community that grows from 200 to 800 members pays more on MailerLite at each tier boundary, while the same community on GroupPost pays based only on how many messages it sends per month — the member count has no pricing impact. GroupPost's free plan covers up to 100 messages per month with no subscriber ceiling, no credit card required, and every feature unlocked — enough to run a real send to your list and evaluate the platform properly before spending anything. Paid plans start at $5/month for up to 1,000 messages and $9/month for up to 5,000 messages. A club with 800 members that sends weekly could handle the entire year on the $5 Starter plan.
Does GroupPost have templates like MailerLite?
GroupPost includes a rich-text message editor with system starter templates and the ability to save your own reusable templates — so you can maintain consistent formatting and branding across messages without recreating them each time. What it does not have is a drag-and-drop library of HTML marketing templates. This is intentional: the primary inbox delivery that GroupPost achieves depends partly on messages looking like email from a real person or organization, not from a marketing platform. HTML-heavy templates with tracked links and branded headers trigger Gmail's Promotions tab classifier. If you need professionally designed email templates for conversion-focused campaigns, MailerLite is the better choice. If you need operational announcements to land in the primary inbox and reach members reliably, GroupPost's formatting approach is an advantage, not a limitation.
I want better open rates — should I use A/B testing or switch to GroupPost?
It depends on why your open rates are low. If you have a disengaged list or unclear messaging, A/B testing subject lines is a legitimate way to improve performance. But if you have an engaged community — members who joined because they want to hear from you — and your open rates are still disappointing, the Promotions tab is the more likely culprit. A/B testing cannot overcome the open rate penalty of landing in the wrong inbox tab. Switching from a marketing platform to GroupPost moves your messages to the primary inbox, which for engaged community lists typically produces a larger open rate improvement than any amount of subject line optimization. The fastest path to better opens for a willing audience is inbox placement, not message testing.
Is MailerLite good for nonprofits?
MailerLite is genuinely well-suited for nonprofits that use email for fundraising campaigns, donor newsletters, and audience growth — functions that benefit from MailerLite's templates, automation, and conversion analytics. MailerLite offers a 30% discount on all paid plans for verified nonprofits, and the platform has a strong track record with nonprofit users. However, nonprofits that primarily use email for operational communication — volunteer coordination, member announcements, event logistics — are often better served by GroupPost, where inbox delivery is more reliable and pricing doesn't scale with list size. Many nonprofits use both: MailerLite for external donor-facing campaigns and GroupPost for internal operational communication.
Does GroupPost support scheduled and recurring sends?
Yes. GroupPost supports both one-time scheduled sends and recurring sends on weekly, biweekly, or monthly schedules. For organizations that send a regular bulletin — a weekly club update, a monthly HOA newsletter, a biweekly volunteer digest — you can set the schedule once and GroupPost handles the rest. Recurring sends can be paused and resumed at any time, and the summary page shows the history of each send batch with open and delivery data per run.
