Simple SMTP by [Maileroo](https://maileroo.com) is here to solve that! This plugin is designed to ensure your WordPress emails are sent reliably and efficiently, using your preferred SMTP service. We aim to simplify and secure email delivery, ensuring your messages consistently land in the inbox. Simple SMTP by Maileroo fixes your email reliability by helping you switch to a proper SMTP Relay such as Maileroo, MailGun, SendGrid, etc. Simple SMTP by Maileroo is free to use and has everything you need to send your emails via WordPress! #### SMTP Explained SMTP, or Simple Mail Transfer Protocol, is the industry standard for sending emails across the internet. It plays a critical role in the email delivery process, acting as the protocol that governs the transmission of emails from one server to another. Understanding SMTP is essential for anyone managing email communications, particularly in a WordPress environment. If you do not use a proper SMTP relay service, your emails might go to spam, compromising their effectiveness and reach. #### HTTP API Integration Now, with the latest update, Simple SMTP by Maileroo offers HTTP API integration with Maileroo. This feature allows you to send emails via the Maileroo API, without the need for SMTP credentials. This is a great option for users whose hosting providers block SMTP ports or for those who prefer to use the Maileroo API for email delivery. #### SMTP Relay Providers Here are some of the popular SMTP Relay providers, each offering unique features and benefits for different email delivery needs: 1. [Maileroo](https://maileroo.com) 2. [Mailgun](https://www.mailgun.com) 3. [SendGrid](https://sendgrid.com) 4. [Amazon SES](https://aws.amazon.com/ses/) 5. [SMTP.com](https://www.smtp.com) 6.

For the SMTP method of the plugin, you can easily add custom mail headers. In the example below, a tag header with the value of the ”From Email” is added: ``` add_action('ssbm_add_custom_header', function($phpmailer) { $phpmailer->addCustomHeader('X-Tag-from', $phpmailer->From); }); ``` A similar filter hook is available for the Maileroo API method. The following example adds the same tag header to the email message. ``` add_filter('ssbm_add_tags_api_method', function($payload) { if (isset($payload['from']['address'])) { $payload['tags'] = array('from' => $payload['from']['address']); } return $payload; }); ``` ## Arvostelut ![](https://secure.gravatar.com/avatar/b49c382cd6f7ce6117979c9f975b73076ce1add9187f2d65ba768febaa05cb22? s=60&d=retro&r=g) ### 󠀁[Maileroo and this pluging – fantastic!](https://wordpress.org/support/topic/maileroo-and-this-pluging-fantastic/)󠁿 [Vizou](https://profiles.wordpress.org/vizou/) 28.10.2025 1 reply This plugin works fantastically with Maileroo API or SMTP. I use it with Formidable Forms on several sites and it not only works perfectly, when it was first released, the developers kept improving it quickly and responded immediately to any questions I had. Highly recommended! ![](https://secure.gravatar.com/avatar/27df198e56ec3056fd4cac9888b622c8d7abcf6e61ecdca2e54942c201a98822? s=60&d=retro&r=g) ### 󠀁[Simple SMTP plugin that works perfectly with Maileroo!](https://wordpress.org/support/topic/simple-smtp-plugin-that-works-perfectly-with-maileroo/)󠁿 [richward1](https://profiles.wordpress.org/richward1/) 17.10.2025 1 reply I'm surprised this SMTP plugin hasn't had more reviews or usage to date because I found it really easy to set up and use with its own Maileroo SMTP service. I've been looking for an easy SMTP setup for my client websites for them to receive form submission notifications. I want to use an API rather than username and password for better security and reliability. My clients have various email providers so I want something I can use for all of them. I like SMTP2Go but it is limited to 5 sending domains for its free SMTP service. I found Fluent SMTP very reliable to connect to other SMTP services but it has a limited number of services that it can connect to using API. I recommend this and Maileroo to anyone looking for a similar solution to reliably send form submissions from their sites. ![](https://secure.gravatar.com/avatar/ed4bec46dd1607b9fcf368c5cd0c97efcac300b27e788a8cd333ec1dc9b4bdf0? s=60&d=retro&r=g) ### 󠀁[Easy and quick setup!](https://wordpress.org/support/topic/easy-and-quick-setuo/)󠁿 [Olaf Lederer](https://profiles.wordpress.org/finalwebsites/) 18.12.2024 I'm using the Maileroo API option and emails are delivered so fast!Excellent SMTP Relay service and a nice plugin. ![](https://secure.gravatar.com/avatar/ff610367bf5eabccb18fb771cff36c664e04db9b9566f6c5113a7a23d75a107d? s=60&d=retro&r=g) ### 󠀁[Simple, no fluff](https://wordpress.org/support/topic/simple-no-fluff/)󠁿 [2000px](https://profiles.wordpress.org/2000px/) 29.11.2024 Enter API key/SMTP settings, set senders details and test connection.That's really all the plugin need to do and this does it.
