My WordPress blog does not send any more email: how to correct this error

Divi: the easiest WordPress theme to use

With over 901.000 downloads, Divi is the most popular WordPress theme in the world. It is complete, easy to use and comes with more than 62 free templates. [Recommended]

This is a frequently asked question by beginners. There are many reasons why your blog no longer sends email. All of this comes from your hosting service.

Are you dedicated or shared?

Shared hosting services set up Several techniques to combat spam, this is why analyzes are carried out on all outgoing mails in order to detect spam content.

The concern is that I can not tell you exactly what words or phrases lead to putting your email in the blacklist (so not sent).

Only let me reiterate what I have already had to recommend in the past: Don't use WordPress for your newsletter (unless you have a dedicated server).

The reasons for this recommendation are clearly explained in an article we wrote.

So it's best to use third-party services to manage your newsletter, and on occasion, I recommend our tutorial on AWeber et MailChimp .

In this tutorial, in addition to the email marketing services that we have already offered you, I will show you how to send emails with Mandrill, which is another service developed by the MailChimp team.

Unlike Mailchimp, Mandrill is only used to send emails, so no templates or predefined campaign programming, which gives you absolute control. Like MailChimp, Mandrill is free up to a sending quota (free up to 12 emails per month).

Using WordPress Mandrill

We will first start by downloading and installing the plugin " wpMandrill On (you can also install it from your dashboard).

After installing the plugin, you need to create a Mandrill account

  1. Hi

    How to insert a list? is it possible ? I can't find the option after installing the wpMandrill Plugin of course and having carried out a test. I have the impression that we can only manually write the contacts to whom to send emails ...
