I have been in business with many online companies for over 8 years and GetResponse is one of the worst I have dealt with. The DMARC, DKIM and SPF records they told me to add were incorrect which wasted masses of time to get set up in the first place and the customer support took over a day to reply every time and this was to say it's our fault and add them again. I managed to fix this using chat GPT in the end as it found the errors in their code but since they were wrong while making the test emails this caused the domain and email to get issues. Finally, we got it set up and sent out the first email batches. I have an email list that I built up from sign-ups on my site and from customers of over 13k. After one email was sent they suspended the account for landing in the spam 3 times out of 13k emails. They then said they would need to clean my emailing list and they deleted 10,500 emails saying that only the ones that opened any emails in the last 12 months can stay. Even though we had been with them for 2 weeks and the 2,500 they didn't delete were the ones that opened the test/ first email.It took them 2 weeks to give me any answer at all by which time the month was up and they tried to force me to pay another month otherwise they would block the account and stop me from exporting anything. They also shut off live support for me during this time.DO NOT USE GETRESPONSE. There's much better and cheaper companies out there.
