If you choose a managed hosting provider, they don’t typically offer email hosting, which means you will need a plugin like Post SMTP to handle your email deliverability process.

One of the main advantages of a managed hosting provider that takes care of the technical aspects of your website, such as backups, security, updates, and performance optimization.

Essential communication

Email is an essential communication tool for any website, whether you want to send newsletters, notifications, confirmations, or contact forms. However, email delivery can be a tricky process, especially if you’re not familiar with SMTP (Simple Mail Transfer Protocol), the standard communication protocol for email transmission over the internet.

SMTP requires a set of parameters to be properly configured, such as the sender email address, the SMTP server hostname, the port number, the encryption method, the authentication credentials, and more.

Which plugin to use?

That’s where Post SMTP comes in handy. Post SMTP is a free WordPress plugin that helps you configure and test your SMTP settings to ensure reliable email delivery. With Post SMTP, you can easily set up multiple SMTP connections, each with its own settings, and choose the one that suits your needs.

For example, you can use your Gmail account to send emails from your website, or you can use a dedicated SMTP service like Sendinblue, Mailgun, or SendGrid.


Post SMTP also offers a range of advanced features to improve your email deliverability, such as:

  • Email logging: Post SMTP keeps a record of all your outgoing emails, including the status, the recipient, the subject, and the content. You can use this log to troubleshoot any delivery issues or to track your email performance.

  • Email templates: Post SMTP allows you to create custom email templates for various scenarios, such as welcome messages, password resets, or order confirmations. You can use placeholders to personalize your emails with dynamic content, such as the user’s name, the order ID, or the date.

  • Email authentication: Post SMTP supports various email authentication methods, such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance). These methods help prevent spam and phishing attacks and increase your email trustworthiness.

  • Email throttling: Post SMTP lets you control the rate at which your emails are sent, to avoid overloading your SMTP server or triggering spam filters. You can set a maximum number of emails per hour or per day, or you can use a smart algorithm that adapts to your SMTP provider’s policies.


Overall, Post SMTP is a must-have plugin for any WordPress website that needs reliable email delivery. Whether you’re using a managed host or a self-hosted solution, Post SMTP can save you time, money, and headaches by simplifying the email configuration process and providing powerful tools to manage your email traffic. Give it a try and see how it can boost your website’s communication capabilities.
