Setting up Custom SMTP (including Gmail OAuth / Outlook or Office 365 OAuth)

Custom SMTP Authentication

Re:amaze can be configured to send directly from your own email server. By doing this, you can own the deliverability and signing of all email replies that are sent to your customers.

To get started, you can enable Custom SMTP for any individual email channel under Settings > Channels. You'll need your email server hostname port domain, username, and password to authenticate. Re:amaze supports SMTP over TLS if you're using a secure email server (which we highly recommend).

Removing the "via Reamaze" or "on behalf of" snippet

The "via Re:amaze" snippet is because of DKIM signing on our SMTP servers. Many email services will display this when Re:amaze's email servers are sending emails on behalf of your domain. Enabling Custom SMTP will remove this snippet from your emails.

Gmail and G Suite OAuth

If you're using Google solutions such as Gmail or G Suite, enabling Custom SMTP can be done easily after your email forwarding has been set up.

When you've completed the step above, go to Re:amaze Settings > Email Channels > Edit > Custom SMTP and enable this option. Select the Gmail option and click on the "Connect" button.

Gmail and G Suite Aliases

If you want to send with a different From address than the username that you're using to authenticate into your Custom SMTP account, you'll need to make sure you have the sending emails added properly in Google Mail. By default, aliases can only receive, but cannot send.

You can add a sending alias by going to Settings -> Accounts -> Send mail as -> Add another email address you own -> And then adding the email alias.

See the following screenshot for a visual reference:

Microsoft Outlook / Office 365 OAuth

If you're using Microsoft solutions such as Outlook or Office 365, enabling Custom SMTP can be done easily after your email forwarding has been set up.

When you've completed the step above, go to Re:amaze Settings > Email Channels > Edit > Custom SMTP and enable this option. Select the Microsoft Outlook / Office 365 option and click on the "Connect" button.
