Gradient Hosting Sending Policies
Our outgoing email service (SMTP) policies play an important role in ensuring Gradient Hosting remains a trusted and reliable email provider.
Simultaneous Recipients
Outgoing emails are limited to a maximum of 256 recipients per email, however we do not recommend sending a single mail with more than 50 recipients, since receiving mail servers may choose to blacklist your address as spam.
Message Size
The maximum size of one outgoing email message is 256 MB, however as with recipients, we do not recommend sending a single mail larger than 30 MB, as receiving mail servers or mail clients may block it.
Spam
You are not permitted to send outgoing email that violates the CAN-SPAM Act. For more information on how Gradient Hosting handles incoming spam, take a look at our Anti-Spam Guide.
We are constantly changing and improving our services, therefore these policies and limits are subject to change at any time.
