MailWizz + MailGun = 26 emails sent, the rest always goes to GIVEUP


New Member
I did 5-6 tests with 50 subscribers and using MailGun (free version). Each time I thought half the list was bouncing or not working because SENT would say 100% and DELIVERED would say 26/50.

So it seems like there is a limit of 25 emails in a blast, then when the 26th one hits...I get put on a pause and the remaining 24 emails go to GIVEUP status.

1) MailWizz - I decreased all my sending limits significantly - made everything send only 10 emails at a time, 10 per minute, 10 second pause, etc. Still no fix.

2) MailGun - I went to look at MailGun's logs to see what was happening - it seems like those additional 24 emails never even hit the MailGun servers (or they hit and immediately got held back due to limit/quota?). When I told MailWizz to resend the GIVEUPs, then I saw MailGun list those additional emails.

Does anyone know where this 25-26 email limit is coming from?

Disregard...limits are from MailGun. They do it for your safety to warm up the domains etc. They just don't tell you exactly how many will be within each limit.
