The first step to building a successful list is to get permission from subscribers who want to receive your campaigns. Permission is not only common courtesy, it’s required by international law and our Terms of Use. Make sure your mailing list consist only of contacts who have expressed their permission to receive marketing emails from you.

Consequences without permission

People who haven't given you permission are more likely to report your campaigns as spam, and less likely to engage with your campaigns or make purchases. It’s in your best interest to always secure express permission.

Spam reports can lead to aggressive spam filtering or blacklisting, which makes it impossible for some subscribers to receive any of your campaigns. This can also damage Omnisend's reputation as a whole and negatively affect delivery for all our users, thus we might terminate your Omnisend account.

Spam reports

When someone reports an email as spam, their inbox notifies their internet service provider (ISP) that the message in question looks suspicious. The ISP then tracks how many people on their network report emails from the sending domain as spam.

Your recipients are also more likely to mark your emails as spam if they’re not familiar with your company. Make sure these labels are clearly tied to your brand, and send campaigns regularly so subscribers don’t forget who you are. You should always include a permission reminder in your campaign footer.

Examples of compliant and non-compliant mailing lists

Here are few examples for you to better understand which lists are allowed in Omnisend, which ones aren’t.
