At WP Engine we want to focus on what we’re great at: providing our customers with the fastest and most secure premium WordPress hosting experience. By offloading email campaigns and blasts to an external service you help protect the security and performance of the server your site is using.
To ensure server stability we impose a hard limit on the amount of emails that can be sent in an hour. In order to prevent abuse of this limit, we will not share the exact amount. The limit is enough to send a functional amount of emails such as password resets, but will not support a full email campaign.
For robust email functionality, monitoring and scalability, we highly suggest customers utilize a 3rd Party email host such as Gmail, MailChimp or Sendgrid which have their own email API. There are several primary reasons why:
- If any emails sent are flagged as spam, this is reflected back on your IP address. Standard emails generated via WordPress are sent from our IP infrastructure (think “password reset”). If those IP addresses ever get blacklisted for spam, it will adversely affect a large number of customers.
- When you send an email blast, you also want to ensure deliverability and tracking. An email host specializes in monitoring and logging email transactions on your behalf. Tracking IP addresses to make sure emails reach their destination is part of their business, just like managing the scalability of your high traffic WordPress sites is ours.
- Default WordPress emails are generated by a command line service. The service generating these emails is generic and doesn’t actually allow us to manage and ensure deliverability. Rather than sending system emails on the server with that basic software, we actually also use a 3rd party managed SMTP provider. This ensures a high level of deliverability and consistency, even for WordPress system emails. Those little details make a big difference for the sites you choose to host with us.
- WP Engine’s servers are not optimized for sending mail. This means we do not have logs or monitoring available if you experience issues with emails not sending correctly. More robust logging, spam control and scalability can only come from a true email host.
Email best practice
WordPress is a great tool, and there’s almost no limit to the things you can build with it. However, just because you can send emails with WordPress, it does not mean you should. In a best practice environment, there are specialized services that are a complete email solution for your business, and will provide you with the optimal results.
While it’s possible WP Engine could add full email services and charge you for it, we want to refer that business to other providers to ensure the best results for you. In the same way we don’t host your DNS, we also don’t host your email. We’d rather focus on what we’re good at: Being a premium platform for awesome WordPress sites.
