Terrible deliverability
I bought Acumbamail during the previous deal, but I didn't really use it until recently. Our first campaign was one that did not use our current list, but had a fresh subscription. Once we launched the campaign to 100% new, opt-in, subscribers (who theoretically would have been waiting for our campaign because that's why they subscribed, specifically) we saw horrible open rates. I actually thought it was just the campaign and maybe the subscribers were just not engaging. But after reading the reviews here and how many others were experiencing low percentages, I had a second think.
(Oh, by "horrible", I mean the last time we ran a similar campaign using a different company, the open rate was 5x better.
So, before running our next campaign, I decided to create a whole new list with specific emails belonging 100% to people I know so I could see if the emails were even making it to the inboxes. Gmail put them in spam. We have all the "deliverability" settings in place: DKIM, SPF, DMARC, and an average to above-average deliverability and open rate using a different service.
Acumbamail offers some pretty strong features, even if the UI is a bit outdated as are some of the templates: Integrations, landing pages, etc. Plus, the ease of use is great, (even if it does revert back to Spanish at times; it is a Spain-based company, after all, so it's only understandable that Spanish would be its default). Never had any trouble navigating the site or setting up emails, etc. If it werent for the deliverabilty issues, I'd recommend this highly.
But, if the emails don't end up in inboxes, the service is useless. Hence the one taco. Get my emails into inboxes and the 1 would go to a 5.

Thank you for sharing your experience — we truly appreciate the honest feedback. We’re sorry for the deliverability issues you’ve encountered, and our team would be happy to review your setup to identify what might be causing emails to land in spam.
It’s also important to highlight that the quality of your lists and how those contacts were collected plays a crucial role in deliverability. Using methods such as double opt-in helps ensure that only engaged, valid subscribers are added, reducing the risk of low-quality contacts that can hurt overall inbox placement.
If you’re open to it, please reach out to us through support and mention your test results — we’ll take a closer look and work with you to improve deliverability. We want your experience to match the value you expected, and we’d love the chance to turn that 1 taco into a 5.
Thanks again for your feedback.
