Hello, I am currently using an emailing tool + SMTP of a web host to send to my cold emailing lists, which is well segmented and verified ! I've been successful with these sendings for quite a few months now, i've taken my time with my daily sendings and warming up. I am currently sending from Monday till Saturday 400 emails everyday. But i cannot keep this slow pace, i absolutely need to increase my daily sending volume from 400 emails to 1000 emails. So i would like to know how can if i change that volume overnight will that cause me some troubles, any suggestions how i can increase the number of my sending volume ? Your help and suggestions are much appreciated ! Thank you.
