We have set a limit for the number of emails you can send per hour.
What is the limit for the number of emails?
This limit is set at 250 emails per hour per hosting package.
Why this limit?
It is a way to prevent spam.
Sometimes the login credentials for an email account or hosting package are stolen. These credentials are often misused to send spam.
When large amounts of email are sent, a shared server can end up on a spam list. If that happens, none of the server's customers can send mail anymore, and we obviously want to prevent that from happening at all times.
What happens if you reach this limit?
If you reach the limit, you will notice that outgoing email traffic will come to a halt. In that case, you will receive so-called "bounce notifications" stating that your email cannot be delivered anymore. This way, someone who wants to send spam will get stuck relatively quickly. This limits the damage that can be caused by the spam sender.
You can adjust this limit downwards yourself. Increasing this limit is not possible to prevent inconvenience for others.
Web hosting is not designed for sending large amounts of messages. If you want to do that, you can use specialized services. They will also provide you with more insight into the reach and effectiveness of your mailing. Common services for this purpose are, for example: SendGrid, Mailgun, SendinBlue or Mailchimp. Some of these services can even be directly integrated within WordPress, which improves user-friendliness.
