Don't buy it!!
We just purchased License Tier 5 (Lifetime access) 2 days ago. Today we are doing the first email campaign. The subscriber list has been optimized and cleaned using Acumbamail's pro tool, with 95% good rating, yet Acumbamail stopped the campaign saying that they "detect a high number of emails that do not exist or complaints" and demand us to pay 113 euros so they can clean the list and reactivate the campaign!
I'm asking for a refund.

Dec 1, 2025Hello,
Campaigns are canceled as a security measure when there is a concern about low-quality lists.
There are several reasons why this can happen, including sending campaigns to non-existent subscribers, having subscribers mark your emails as spam, or if more than 20% of the emails in your campaign result in bounces. Both of these actions are highly detrimental and associated with spammer practices, which can cause ISPs to categorize your domain as a spam source for future campaigns. This is because it signals that the quality of your lists is low.
If you would like further advice on how to improve the quality of your list, please feel free to contact us at support@acumbamail.com. We’d be happy to provide recommendations.
Best regards,
