Resolve a Newsletter blockage

This guide explains why sending an Infomaniak Newsletter might be blocked and how to proceed with sending it.

Why block the sending of a newsletter?

Please be aware of the following measures:

• The sending of a newsletter may be blocked if too many recipient email addresses are invalid
• The sending of a newsletter may be blocked if the SPAM rate is too high
• After a blockage, it is necessary to contact Infomaniak support to be able to complete the blocked sending

How to avoid being blocked?

• Use only contact lists that you have built yourself
• Build your contact lists with double opt-in forms
• Remove contacts you haven't emailed in over 6 months; less-used contact lists are more likely to contain outdated email addresses‍
• If needed, automatically clean your subscriber lists with services like NeverBounce, Bounceless, or QuickEmailVerification
