Still in the process of making a decision for a new Email Service Provider. Looking at Acumbamail for their focus on the emails and curating the e-mail lists. With the option for unlimited contacts and an unlimited number of lists. Whit a licensing model based on the number of emails per month.
Like the way, the information is presented on the platform. Also great is that the e-mails delivered from the platform are non-branded by the provider, which is a great benefit for me.
Getting started is a bit easier than I faced with other platforms. Might also come with the clear focus on the e-mail lists and the Landing Pages. For me the main focus is on the e-mails. For the landing pages I will use the Thrive Suite I have in place. In that sense I also hope that there will be soon a native integration with Thrive. This would save even more time.

You can still see that the platform was developed for the Spanish market first, with some of the support materials landing on Spanish content. Expect that this will be fixed soon. So it gets even easier to use.

The platform is fast and responsive in using. Uploading the contacts via CSV files is very easy, the platform recognizes the columns in the CSV and lets you decide on what to import to what fields in Acumbamail.

Looks very promising, now just a bit of work to get the existing e-mail lists converted to Acumbamail and to get the auto responders setup correctly. Hope that the native integration with Thrive Suite will be there soon, so I can remove the intermediate step I now have to build in as well.
