To keep systems healthy and accounts safe, Hostinger limits the number of emails you can send per day, per hour, and the number of recipients per message on cPanel email:

* Up to available resources – you can create as many email accounts as needed within your hosting plan storage and resource limits.

The sending limits apply to the total number of messages sent via SMTP and PHP from all email accounts on your hosting plan, based on your specific cPanel plan:

Once you reach either of these limits, the sending capabilities of your hosting plan will be automatically disabled. To avoid this, especially if you plan to send large volumes of email (like in an email marketing campaign), consider these alternatives:

Deferred emails are messages delayed due to issues like invalid recipient addresses or blocks from anti-spam or firewall protections.

The maximum limit for deferred emails is five (5) per hour. If your account reaches this limit, additional messages will not be sent until the limit resets one hour after it was reached.

To avoid hitting this limit, ensure that the addresses you’re sending to are valid and that you maintain a good sending reputation.
