Plugin WordPress de correo SMTP
Is your WordPress site not sending emails? You’re not alone. 3+ million websites use WP Mail SMTP to send emails reliably.
Our goal is to make email deliverability easy so that your emails always reach the inbox.
WP Mail SMTP fixes your email deliverability issues by reconfiguring WordPress to use a proper SMTP provider when sending emails.
Best of all, our easy-to-use Setup Wizard and detailed documentation guide you through the process.
WP Mail SMTP is free and has everything you need to reliably send your WordPress emails!
WP Mail SMTP Pro unlocks even more powerful features like email logging, advanced email reporting and stats, backup connections, email alerts, smart conditional routing, and much more.
¿Qué es SMTP?
SMTP (Simple Mail Transfer Protocol) is an industry-standard for sending emails. Proper SMTP configuration helps increase email deliverability by adding authentication to the emails sent from your site.
Popular email clients like Gmail, Yahoo, Office 365, and Zoho are in a constant battle with email spammers, so they check whether emails are originating from a genuine sender. If the proper authentication isn’t there, emails either go in the SPAM folder or, worse, disappear.
This is a problem for a lot of WordPress sites. By default, WordPress uses the PHP mail function to send emails generated by WordPress or any contact form plugin like WPForms.
But most WordPress hosting companies don’t have their servers properly configured for sending PHP emails.
This is why WordPress emails aren’t delivered.
¿Cómo funciona WP Mail SMTP?
WP Mail SMTP plugin easily resolves email delivery problems by changing the way your WordPress site sends email. We reconfigure the wp_mail() function to use proper SMTP host credentials or an SMTP mail provider.
With our built-in SMTP mail provider integrations (recommended), emails are sent using the provider’s direct API. Even if your web host is blocking SMTP ports, your emails will still be sent successfully.
This helps you fix all WordPress not sending email issues.
WP Mail SMTP plugin includes many different SMTP mailers:
- SendLayer (#1 Recommended)
- SMTP.com (Recomendado)
- Brevo (formerly Sendinblue) SMTP (Recommended)
- SMTP de Mailgun
- SMTP de SendGrid
- Postmark SMTP
- SMTP de SparkPost
- SMTP de Gmail (Gmail, Google Workspace, G Suite)
- Microsoft SMTP (Outlook.com and Office 365) [Pro]
- Amazon SES SMTP [Pro]
- Zoho Mail SMTP [Pro]
- Otros SMTP
For most options, you can specify the “from name” and “email address” for outgoing emails too.
All of these powerful features make WP Mail SMTP the best SMTP solution for WordPress.

WP Mail SMTP allows you to specify the maximum number of emails that will be sent every minute, hour, day, week, or month and automatically queues emails to stay within those limits.

Is WP Mail SMTP available in other languages?
-
We know that majority of people do not speak English, so we professionally translated WP Mail SMTP and WP Mail SMTP Pro into the following languages:
- Spanish (Spain),
- German,
- Portuguese (Brazil),
- Italian,
- French,
- Japanese,
- Polish,
- Dutch,
- Russian,
- Turkish
-
How can I increase plugin security?
-
The WP Mail SMTP team takes security very seriously. Not only does the plugin follow all security best practices, but we have several options available to ensure your site is safe and secure.
-
Direct SMTP mailer integrations (recommended), such as SendLayer, SMTP.com, Brevo (formerly Sendinblue), Mailgun, SendGrid, Postmark and SparkPost, use the official provider APIs. This means you never enter your username or password in the plugin settings and these credentials are not stored in the database. Instead, we use tokens or API keys which are much more secure.
-
When using Other SMTP mailer, we provide the option to insert your password in your
wp-config.phpfile, so it’s not visible in your WordPress settings or saved in the database.
-
-
I found a bug, now what?
-
If you’ve stumbled upon a bug, the best place to report it is in the WP Mail SMTP GitHub repository. GitHub is where the plugin is actively developed, and posting there will get your issue quickly seen by our developers (myself and Slava). Once posted, we’ll review your bug report and triage the bug. When creating an issue, the more details you can add to your report, the faster the bug can be solved.
-
