I really wonder how did sendinblue allowed cold mailing in the 1st place. Your doing warmup from many days ?

Checkout marketplace you will find many ..

Good luck

I use https://vibeleads.com

a slight learning curve at first and give unlimited data.

instantly ai best imo. Unlimited warmup is what you need when dealing with cold emails

Always verify and clean your email lists before sending even if fresh or 1sh hand.
