SMTP – 100% Free & Open Source SMTP plugin for WordPress – Bit SMTP

Description

Easiest SMTP Plugin for WordPress. It’s FREE and easy to setup.

A lot of site owners face the spam mail problem for using the WordPress default PHP mail function(). When it comes to mail service there may be some restrictions: sometimes emails are not delivered, sites cross the limit of outgoing mail.

Bit SMTP plugin allows you to authenticate the mail service of your site by configuring the SMTP server of your desired mail service. SMTP is a protocol that helps your WordPress site to make its email deliverability more easygoing & reliable. By enabling this feature you can send mail from your site to your recipients via your preferred mail server.

How does SMTP work:

At first, you have to open an account on your desired hosting provider (e.g: MailGun, Gmail, Yahoo, Hotmail, Zoho mail). By opening an account you are authenticating your WordPress site. They will provide you with the necessary credentials (e.g.: Encryption type, SMTP port ). You have to put this information when configuring SMTP on your site. Once your site is authenticated you can send mail through your preferred SMTP server. All the email validation work will be done on your specified SMTP server.

To access all the mail services you need professional mail addresses. The mail services you can use through this plug-in:

  1. MailGun SMTP [5,000 free email /per month for 3 months]

For recommended direct SMTP mailers integrations like SMTP.com, Brevo (formerly Sendinblue), Mailgun, SendGrid, Postmark, and SparkPost, we utilize official provider APIs.

Mismatch with screenshot. No opportunity for GMail integration

Simple to use and does the job it’s supposed to do. Note that you need to use the right settings for it to actually work though, which can be a bit tricky if you don’t know your SMTP settings.

Installed and activated this plug in. Receive a message stating SMTP settings correct and established connection to ZOHO server. Tried sending 3 test emails; each email failed to send. Could not disable and remove plug in fast enough. If you want to waste time, this is a good way to do so but I prefer to watch the grass grow.

Can not get it to work with SMTP using SSL. Send test says “sent succesfully” but no, no log or error message and does not really send.
