Pros / Cons
- I like that ProtonMail doesn’t track me or read my emails, which is important when I’m dealing with lead lists or supplier conversations.
- There’s no real integration with tools like ActiveCampaign (my email solution) or Google Sheets (my data solution), which makes it harder for me to slip it into my broader marketing stack.

- An excellent service that despite the somewhat difficult initial curve in understanding all the functions and how to get the most out of it then really becomes a well-structured service with all the necessary functions to control and manage the sending of e-mails.
- I wasn't able to completely refactor the integration before the cutoff, so now I have no automation and they deleted all my contacts and my templates, so I get to rebuild ALL of that from scratch.
