How to configure a test SMTP integration for Retool


If you're building a no-code tool using Retool and you're using the SMTP integration you will want to send test emails during development.

Retool enables you to specify your own SMTP settings when you set up the SMTP resource. Setting up Imitate Email as your SMTP server is very easy to do:

Step 1: Set up Imitate Email

If you've not already done so please sign up to Imitate Email.

Step 2: Locate your mailbox credentials

Your username

To locate your username go to Settings > My Mailbox where you will find it (it is the same for all mailboxes in your account)

For the password

If you're on the Free or Developer plan or you're setting this up for your personal mailbox copy the password from the same place as the username.

If you're setting this up for a team mailbox go to Settings > Projects and you will find the password next to the symbol for your mailbox. It will look like the following 6bcb69b2-08ac-4c67-911a-10442f7d84b3

  2. Enter a Name for the resource and then:

  • Enter in the Host box
  • Enter 587 in the Port box
  • Copy your username and password from the previous step in to their respective boxes.
