Replying As Your Forwarded Email Address in Gmail
The Problem
By default, when you reply to a forwarded email in Gmail, your reply comes FROM your Gmail address — not your custom domain address. This can be confusing for recipients.
Example: Without SMTP Setup
- Customer emails
support@yourcompany.com - Email forwards to your Gmail:
you@gmail.com - You click Reply in Gmail
- Reply sends FROM
you@gmail.com❌ - Customer sees reply from your personal Gmail (unprofessional!)
Example: With SMTP Setup
- Customer emails
support@yourcompany.com - Email forwards to your Gmail:
you@gmail.com - You click Reply in Gmail
- You select support@yourcompany.com from the "From" dropdown
- Reply sends FROM
support@yourcompany.com✅ - Customer sees reply from your professional address!
The Solution: SMTP Credentials
To reply from your custom email address, Gmail needs permission to send emails through AWS SES on your behalf. This requires SMTP (Simple Mail Transfer Protocol) credentials.
Step 1: Request SMTP Credentials
Send a message to support with:
- Your domain name (e.g.,
yourcompany.com) - The email address you want to send from (e.g.,
contact@yourcompany.com)
You'll receive:
- SMTP Server:
email-smtp.us-east-1.amazonaws.com - Port:
587 - Username:
AKIAU************ - Password:
****************
Step 2: Add Email Address to Gmail
- Open Gmail
- Click the gear icon → See all settings
- Go to the Accounts and Import tab
- Find Send mail as
- Click Add another email address
Step 3: Enter Your Email Information
A popup window will appear:
- Name: Enter your name or company name (e.g., "Support Team" or "John at MyCompany")
- Email address: Enter your forwarding address (e.g.,
contact@yourcompany.com) - UNCHECK "Treat as an alias" — This is important!
- Click Next Step
Step 4: Enter SMTP Settings
Now Gmail will ask for SMTP server details:
- SMTP Server:
email-smtp.us-east-1.amazonaws.com - Port:
587 - Username: Paste the username from Step 1
- Password: Paste the password from Step 1
- Secured connection using TLS: Make sure this is checked ✓
- Click Add Account
Step 5: Verify Your Email Address
- Gmail will send a verification email to
contact@yourcompany.com - Since you have forwarding set up, it will arrive in your Gmail inbox
- Open the verification email
- Click the verification link
- Done! ✅
Step 6: Using Your Custom Address
When composing or replying to emails:
- Look for the From field at the top of the compose window
- Click the dropdown arrow
- Select contact@yourcompany.com
- Send your email
Recipients will see it came from your professional address!
Troubleshooting
Error: "Email address is not verified"
This usually means there's a region mismatch. The SMTP credentials must be from the same AWS region as your email forwarding setup.
Solution: Contact Formtabulo.us support and request new SMTP credentials for the us-east-1 region.
Error: "Authentication failed"
Double-check your username and password:
- Make sure there are no extra spaces when copying/pasting
- Verify you're using the correct credentials for your domain
- Confirm the port is set to
587(not 465 or 25)
Gmail Doesn't Ask for SMTP Settings
This happens if you leave "Treat as an alias" checked. To fix:
- Delete the email address you just added
- Start over from Step 2
- Make sure to UNCHECK "Treat as an alias"
Verification Email Doesn't Arrive
Check that:
- Your forwarding rule is Active (not Paused)
- The forwarding destination is correct
- Check your Gmail spam folder
Testing Your Setup
Send yourself a test email to verify everything works:
- Send an email from a different account to
contact@yourcompany.com - Check that it arrives in your Gmail inbox ✓
- Click Reply
- Change the "From" field to
contact@yourcompany.com - Send the reply
- Check the other account — reply should show it came from
contact@yourcompany.com✓
Other Email Providers
These instructions are for Gmail, but the same SMTP credentials work with:
- Outlook.com / Hotmail — Settings → View all Outlook settings → Email → Sync email → Connected accounts
- Apple Mail (iPhone/Mac) — Settings → Mail → Accounts → Add Account → Other → Add Mail Account
- Thunderbird — Account Settings → Account Actions → Add Mail Account
The SMTP settings are the same for all email clients — just use the credentials provided by Formtabulo.us.
