hello, I can say that Gumbamail is excellent for me personally, it works, I've been using it for a month, I took code number one, now I'm taking code number two. I had a small problem with entering the code, but the support was great, it was fixed in 1 day, which is completely normal. I started a campaign for several products and my list is 1,698 verified contacts and 417 are opened, the second campaign is 1,627 contacts and 491 messages are opened, the third is 1,637 contacts and 493 messages are opened. I'm new to email marketing, so I think it's good if there is someone who is an expert to give their opinion. Best regards ilia sweden
