Let us start by saying, \u201cThank You!\u201d<\/p>\n\n\n\n

We are moving quickly toward our milestone of 500,000 installations. One ingredient in our secret sauce of success is listening to the feedback we receive from our users. With your help, we have been able to create one of the most trusted email delivery plugins for WordPress on the planet.<\/p>\n\n\n\n

Thank you very much for supporting us. And, now we have a few updates:<\/p>\n\n\n\n

MailerSend (FREE)<\/strong><\/h2>\n\n\n\n

For those who are new, relying on your web host’s default email function is a recipe for disaster, as critical messages like contact form submissions, order confirmations, and password resets can end up lost or in spam. To improve email deliverability<\/strong><\/a> of your WordPress site, you need two things: Post SMTP and an SMTP mailer service.<\/p>\n\n\n\n

Inside Post SMTP, we provide more than 12 free and paid SMTP choices<\/strong><\/a>. We are now adding one more to the mix: MailerSend.<\/p>\n\n\n\n

MailerSend is designed for both developers and non-technical users. The integration with Post SMTP is simple<\/strong><\/a>: you just need to generate an API token and verify your domain from your MailerSend dashboard, then paste the API token into the Post SMTP setup wizard to get started.<\/p>\n\n\n\n

With a generous free plan that includes 3,000 emails per month, MailerSend is perfect for any business that is just starting out. The paid plans aren\u2019t expensive either. The Starter plan gives you 50,000 emails per month for just $35. If you pay annually, you can enjoy additional savings.<\/p>\n\n\n\n

When it comes to deliverability, MailerSend is one of the best SMTP servers, as tested by EmailToolTester<\/strong><\/a>. You can depend on MailerSend for global reach at blazing-fast delivery rates.<\/p>\n\n\n\n

With so much to offer, MailerSend can be the perfect email SMTP provider for your WordPress sites.<\/p>\n\n\n\n

Diagnostic Reporting via Email (FREE)<\/strong><\/h2>\n\n\n\n

Whenever you hit a snag, you reach out to our support team. In most cases, the experts of the Post SMTP support team can fix your issue within 24 to 48 working hours. In some cases, we ask you to generate a diagnostic report and post it on the support channel, where sensitive details about your WordPress installation could be exposed.<\/p>\n\n\n\n

With the all-new Diagnostic Reporting feature, you can now send your diagnostic reports directly to us through email. This ensures all data is visible only to our support team for review and assessment.<\/p>\n\n\n\n

Performance Upgrades<\/p>\n\n\n\n
