I have tried various emailing tools, especially some on Appsumo. There has been nothing but bugs without any fixes.

GoZen Growth has it all. I really like the UI and everything is very accessible. You can upload unlimited contacts via CSV which is cool. Setting up SMPT was a breeze and the warm up functionalities started working straight away. It appears to be more reliable than other services.

Setting up campaigns is very easy too and the workflow automation is advanced and has all the options you will need. There is analytics too for tracking.

There are lots of pre made templates to choose from and you can also create a sign up form too.

Lead finder you need to buy tier 5 to have access to it or you can pay something like $10 per month which is reasonable considering they need to pay for other costs.

Overall I absoutely love GoZen Growth and it will be my go to emailing tool for the future. I can't wait to dive deeper and start sending out some cold emails with all the included features. Thanks.
