How to Send WordPress Emails with Microsoft 365(Office 365)?

Microsoft 365 offers Microsoft Exchange-based hosted email. Exchange is one of the most popular mail service providers for businesses, offering features such as push email and widespread compatibility.

Email marketers can connect Microsoft 365(formerly office 365) to WordPress to ensure better email deliverability, even if they send many of them!

If you’re using Microsoft 365 subscription for your business emails and would like to use the same email for sending WordPress emails, we’ll help you get started. Read this article to learn how to connect and send WordPress emails with Microsoft 365.

What is the Microsoft 365 Mailer?

Microsoft offers email address and inbox services and a tool to improve the deliverability of your emails. They do this through an API, so you don’t have to enter any sensitive login details into your WordPress admin area.

Microsoft offers free service to anyone with their email accounts(example@hotmail.com, example@outlook.com, or a Microsoft 365 email address). It can send up to 1,000 emails per minute, much higher than the limits on most other mailers.

If it’s a good match for your consideration, let’s see why you should consider sending WordPress emails with the Microsoft 365 mailer.

Why should you send WordPress emails with Microsoft 365 Mailer?

To begin with, WordPress is a content management system rather than an email service provider. Users do not receive emails from WordPress.

Many WordPress users report that their emails aren’t delivered to their inboxes. The problem is due to the way WordPress handles email delivery.

Here’s what happens when you send an email from WordPress:

  • The wp mail() function is one of your WordPress files’ core programs. Plugins use the wp mail() method to send emails to WordPress.
  • WordPress sends this email request to your hosting provider’s server, which processes it with PHP email.
  • Finally, PHP instructs the hosting provider’s mail server, and the email router on your server sends the emails to the recipients.

Many hosting providers do not have an email infrastructure, and many hosting servers automatically prohibit PHP emails. That’s why you should never send emails using WordPress. Unfortunately, it’s a familiar yet irritating problem for WordPress users—but one that you can resolve.

The simplest solution is to use an SMTP plugin instead of the PHP mailing system. An SMTP plugin helps you route your emails via an SMTP server. SMTP(Simple Mail Transfer Protocol) is the international standard for sending and receiving emails over the internet.

If your web hosting provider does not offer email hosting, you can use an SMTP plugin to send WordPress emails. Any reliable email sending service such as Gmail/Google Workspace, Amazon SES, MailGun, Microsoft 365, etc., should deliver your emails just fine!

SMTP plugins are easy to set up and utilize. We suggest FluentSMTP for improving email deliverability as it is a free and open-source SMTP plugin for WordPress.

However, setting up an SMTP plugin for beginners can be daunting. But don’t worry; we’ll guide you in setting up Microsoft 365 mailer in FluentSMTP through our step-by-step tutorial.

Things to consider before getting started

The Microsoft 365(WordPress SMTP office 365) setup process is more complex than most other mailer options. There are some requirements before setting up Microsoft 365 as your mailer service.

  • Your site needs to have SSL(HTTPS) enabled. 
  • While Microsoft 365 setup does not require any paid Microsoft services, they will require your credit card details to reduce spam signups.
  • A Microsoft 365 account with admin privileges is needed to grant your application SMTP access. The Global administrator needs to configure the admin consent workflow to set up this mailer without admin privileges.
