How to Set Up the MailPoet Sending Service

After you have signed up for a MailPoet plan that includes sending via our MailPoet Sending Service, your next step will be to set things up on your site.

Activating your license key

First, you will want to go to the MailPoet > Settings > Key Activation tab in your site's administrator dashboard to activate your plan's license key (and install the Premium plugin if you are on a paid plan).

We have a step-by-step guide for activating your key here.

Important: key activation will not work if your website is on localhost or behind a firewall. Please read more about it here.

Every time you validate a key that includes the MailPoet Sending Service, our sending service will be activated as your sending method automatically.  

You can confirm the MailPoet Sending Service is set as your sending method by going to the MailPoet > Settings > Send With... tab:
