Reliable WordPress Email Delivery with WP Mail SMTP
At Genius Computing, we specialise in building and maintaining WordPress websites for our clients. One of the most common issues we see is WordPress email delivery failures, where contact form submissions or automated notification emails never make it to the recipient’s inbox.
This isn’t just frustrating — it can mean missed sales leads, lost enquiries, and unhappy customers.
The fix? WP Mail SMTP.
Why WordPress Sites Struggle with Email Delivery
By default, WordPress uses PHP mail functions to send emails. Unfortunately, these often fail to meet modern authentication standards and are frequently marked as spam — or blocked entirely.
For businesses relying on their WordPress website to handle customer communication, this is a serious problem.
WP Mail SMTP solves this by reconfiguring your WordPress site to send emails the right way — using secure authentication methods like OAuth with trusted providers such as Microsoft 365.
Office 365 Is Deprecating SMTP Credentials for WordPress Email Delivery
If your WordPress website is set up to send emails through Office 365 using a simple SMTP username and password, it won’t work for much longer.
Microsoft is deprecating this method of authentication, and once it’s removed, any WordPress site still relying on SMTP credentials will stop sending emails.
The Pro version of WP Mail SMTP includes built-in support for Office 365 OAuth connectivity, meaning your WordPress site can continue sending emails securely — without interruption.
Why Choose WP Mail SMTP Pro for WordPress Email Delivery
While the free version of WP Mail SMTP is useful, we strongly recommend the Pro version for business WordPress sites, especially those connected to Office 365. It offers:
- Office 365 OAuth Support – Future-proofs your WordPress site against Microsoft’s changes
- Email Logging – Track every email sent from your site
- Email Alerts – Be notified if your site fails to send an email
- Priority Support – Expert help when you need it
This ensures your WordPress site continues to deliver enquiries, confirmations, and notifications without fail.
