Docs > White-Label Email (SMTP)
If you resell WebAbility under your own brand, your users get account emails: password resets, invitations, welcome emails and reports. Connect your own SMTP server and these emails come from your domain, with your organization name in the sender and the subject.
Only organization owners see these settings. Without your own SMTP, emails already use your organization name in the sender and subject, but they come from our sending domain.
You need a host, a port, an encryption type, a username and a password. Common values:
| Provider | Host | Port | Encryption | Note |
|---|---|---|---|---|
| Google Workspace | smtp.gmail.com | 587 | None (STARTTLS) | Use an app password, not your normal password. |
| Microsoft 365 | smtp.office365.com | 587 | None (STARTTLS) | SMTP AUTH must be on for the mailbox. Microsoft plans to turn basic SMTP AUTH off by default after December 2026: check with your admin. |
| Amazon SES | email-smtp.<region>.amazonaws.com | 587 | None (STARTTLS) | Use SES SMTP credentials, not IAM keys. A From address is required. |
| Mailgun | smtp.mailgun.org | 587 | None (STARTTLS) | Use the SMTP user for your sending domain. |
| Postmark | smtp.postmarkapp.com | 587 | None (STARTTLS) | User and password are your server API token. A From address is required. |
| SendGrid | smtp.sendgrid.net | 587 | None (STARTTLS) | User is apikey, password is your API key. A From address is required. |
Allowed ports are 587 and 2525. Ports 25 and 465 are blocked on our servers. With encryption "None", the connection still upgrades to TLS (STARTTLS). The host must be a public mail server. Check your provider's own SMTP page for the exact values for your account.
We encrypt the password before we store it, and we never show it again. To keep the saved password, leave the field blank when you change other settings.
By default, emails come from the SMTP user. To use a different address, such as [email protected], enter it in From address.
If your SMTP user is not an email address (Amazon SES, SendGrid and Postmark use keys or tokens), the From address is required. We do not save the settings without it.
Your provider must allow the SMTP user to send as that address. Most providers call this a verified sender, a send-as alias or a verified domain.
Click Send test email. We send one email through your SMTP server to your own account address.
SPF and DKIM tell inbox providers that your mail server may send for your domain. Without them, emails can go to spam. Your email provider gives you the exact DNS records to add.
A password reset that never arrives locks your user out. So if your SMTP server rejects an email, we still send it from our sending domain, with your organization name as the sender.
We record each failure. The Organization page then shows a notice with the time and the error from your server. The notice goes away after the next email your server sends. Click Send test email to check a fix.
Contact us from the contact page. Include the error from the test email, never your SMTP password.
