How to set up custom sender's email (SMTP)

Clustdoc usually takes care of sending all email notifications through the platform. However, you can also send emails to your recipients through your SMTP mail server. 

By allowing you to use your own mail provider, Clustdoc enables you to use email addresses in their own domain to get better open rates and fully manage, monitor, and troubleshoot email delivery.

After you set up your custom email addresses and SMTP servers, you'll be able to change the "From" in the email addresses to your custom address for notifications sent to your recipients.  

Prerequisite for setting up your SMTP

There are three requirements for the SMTP server:

1. It must support LOGIN authentication.
2. It must support TLS 1.0 or higher.
3. It must use a certificate signed by a public certificate authority (CA). 

Setting up your SMTP

To be able to use your own SMTP server:

1. Login in to your Clustdoc account and go to the Custom domain & Email section.
2. Enter your SMTP server Host, Port, Username, and Password in the appropriate fields. (See example below)
3. Click Save

For Gmail users, try to use SMTP Port 587 with TLS. And if your configuration still fails, also deactivate the Gmail 2FA.
