Send one version to 5% of my email list. Send a second version to a different 5% of my email list. Send the better-performing version to the remaining 90% the next day. I don't let it drag out. A/B testing can go on forever!

We've been using SendinBlue, seems to do the job for us

Hello, Lior. A very interesting topic. I never tested my email copies. Is that necessary when you have a ton of marketing emails?

I'm using Mautic (an open-source tool) to send emails for intab.io it takes a little bit of time to set up at first but it's well worth it. has pretty much every feature you will ever need.

We've used Maze to run an A/B test on content (product and email) and send it across to some of our users (here is a helpful guide: https://maze.co/blog/content-tes...). We've also run a qualitative test in calls with our early adopters - can do wonders if you're an early-stage team and don't have a big volume of subscribers to really run an A/B test.

We use Keap.

I try A/B testing at every stage - send A version to a large enough number of users (lets call it X), send B version to another X group of users. See which performed better. Then, send A to X users, send C to X users. See which performed better. Rinse. Repeat. Sometimes attitudes change with no apparent reason and different copies succeed better than others. Try understanding what worked well. The most important thing is to verify that you indeed change only one thing between A and B.

I once used HubSpot

I use Lemlist for my email campaigns

A\B testing is a king :) Also using Grammarly for a content inside

We are using Ecomail.app. It's a very intuitive solution.

Don't forget to check all the grammar mistakes :)

Hi there, I think it's important to test whether or not your copy is effective and indeed leads prospects/users to take the action you'd like them to take. Check
