This article contains instructions on navigating the new version of Elastic Email dashboard. If you would like to see the old dashboard version of this article, please use the following link

Note: Each account can store up to 15 unique SMTP Credentials

Almost all third party SMTP clients, Servers, CMSs and Plugins will use these settings to connect and relay mail through your Elastic Email Account. We don't know of any software that supports SMTP connections that do not work with Elastic Email but there is a list of CMSs and Plugins that are designed to work specifically with our platform.

Create SMTP Credentials

New accounts do not have any SMTP Credentials. Click this button to create a new one.


Your Elastic Email Account SMTP Username defaults to your Elastic Email Account email address that you use to log in. You can use another email address, but it has to be unique across the entire system - just as with account email addresses. Here you can also set IP access restriction.

After clicking the Create button, a pop up will appear with your newly created SMTP Credential details.


A unique password for your SMTP connection. Copy it and save it in a safe place. Once you close this window you will not be able to retrieve it. After this step, our system will obfuscate it except for the last 5 digits for your security reasons.

Server You can either use or

Port We support the following connection ports:

25, 2525, 587, 465

We support TLS 1.2 and SSL connections. Make sure the connection port you are using is open on your own server.

Using Postfix? If you are configuring postfix as a local relay, make sure you include the following three lines in your postfix configuration

smtp_sasl_auth_enable = yes

smtp_sasl_password_maps = static:yourusername:your api key

smtp_sasl_security_options = noanonymous

You can also Edit, Change or Add other SMTP Credentials.
