Setting Up SMTP Credentials for Email Delivery

Modified on Wed, 4 Sep at 12:00 PM

To ensure smooth and reliable email delivery from your domain, creating SMTP (Simple Mail Transfer Protocol) credentials is essential. SMTP facilitates sending emails, while each domain you add will have its own set of credentials. Keep in mind, our platform focuses solely on email transmission and does not support POP or IMAP protocols. This guide will walk you through how to create, reset, and remove SMTP credentials, along with understanding key settings.


Steps for Generating SMTP Credentials


Access Your Domain Settings

Start by navigating to Settings. From there, head to Email Service > SMTP Service > Dedicated Domain and IP. Once you're within the dedicated domain settings, locate the SMTP Settings section.


SMTP Settings

Create a New SMTP User

Next, click the "Create New SMTP User" button.

Provide the username and password required to establish the new SMTP credential.

Note: Each dedicated domain allows you to create up to five SMTP credentials.

SMTP Configuration Settings

To properly configure your SMTP credentials, use the following details:

  • SMTP Server Address: smtp.mailgun.org

  • Secure Connection: TLS/SSL (Depending on your email client or plugin)

  • SMTP Username: [[email protected]]

  • SMTP Password: [YourCreatedPassword]

  • SMTP Ports: 25, 465 (SSL/TLS), 587 (STARTTLS), 2525


Mailgun-Supported Ports:

SMTP vs. IMAP: Key Differences

While SMTP is exclusively used for sending emails, IMAP is employed to retrieve them. As our platform does not host mailboxes, IMAP and POP protocols are not supported. For IMAP settings, you'll need to consult your email provider directly. Here are a few examples for common providers:

  • Google:

    • Generate an app password in Google

    • Username: Your full email address

    • Password: The app password

    • IMAP Host: imap.gmail.com

    • IMAP Port: 993

  • Verizon:

    • IMAP Host: imap.verizon.net

    • IMAP Port: 995

  • AOL:

    • IMAP Host: imap.aol.com

    • IMAP Port: 993

For other providers, refer to their support documentation for precise IMAP configuration.


Managing SMTP Credentials for Seamless Email Operations

Handling your SMTP credentials properly is critical for ensuring secure and effective email transmission from your domain. With the steps above, you can effortlessly create, reset, or delete SMTP credentials as needed. For IMAP settings, please rely on the specific instructions provided by your email service provider.
