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 you your SMTP
There are three requirements for the SMTP server:
- It must support LOGIN authentication.
- It must support TLS 1.0 or higher.
- 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:
- Login into your Clustdoc account and click on your Profile Picture>Set up Team, navigate to Custom domain & SMTP.
- Enter your SMTP server Host, Port, Username and Password in the appropriate fields
For Gmail users, try to use SMTP Port 587 with TLS. And if your configuration still fails, also deactivate the Gmail 2FA.
- How to troubleshoot SMTP?
Here are some tips to troubleshoot the most frequent issues with SMTP and email deliverability. Remember that using a professional SMTP service can help you solve most issues.
- Check again your username and password.
- SMTP normally uses port 25, but it may happen to be blocked by your ISP: try switch to port 587 (or port 465 if you’re connecting via SSL).
- The SMTP settings are mistaken. Maybe you configured your mail client with a wrong outgoing server name.
- Firewall or antivirus issues. Make sure that you have an exception rule for your SMTP service in your firewall, proxy service or antivirus settings.
If you keep running into issues, it’s likely that you have a general issue with your Internet Service Provider (which you should contact immediately).
