Using third party email service

Google Cloud Platform does not allow sending emails via standard SMTP ports (25, 465, and 587) but you can use multiple email services for sending, for example, using Gmail Business as typical email service and another one just for sending, know as transaction email service. There are two possibilities, to use our built-in email service powered by Mailgun or another third-party email service.

Using an email service via HTTP API

To bypass the Google Cloud SMTP limitation, you can use any other email plugin/service that works via API. Zoho mail is a typical email service, used for receiving and sending, it`s free and has a WordPress plugin that works via HTTP API.
