To send recurring emails from your FastMail address using Recurrr, you have to add it as a Channel. Watch this short video or follow the steps below:
In short:
Step 1. Go to your Profile Page and click "Add a new channel". A popup will show up:
Step 2. Inside that popup, choose a name and color for this channel:
a good name would be "FastMail", "CompanyName" or "[email protected]";
a good color would be your brand color;
Step 3. In the "Email Settings" section, enter your email address, and select "Fastmail" as the email provider.
Step 4. A new fieldset has shown up - "Server Settings". Our system has already entered the correct settings for the FastMail SMTP server, so leave it as-is.
Step 5. Another fieldset has shown up - "Login Settings". In here, you need to add your Gmail address and password. For the password, the best thing to do is generate an app password in FastMail:
Log into FastMail, then go to Settings > Security & Privacy > Integrations.
Click the button that says "New app password".
In the form that opens up, pick "Custom" for the name, and put in "Recurrr".
Then for the access choose SMTP. That's all Recurrr needs.
Click "Generate password" and copy-paste it. Go back to the Recurrr form, and paste the password there. Click "Save Channel" and...
That's it, you're done! You can now send emails on schedule from your FastMail address. Click the Compose button in the top-right corner of the screen.
