WARNING: Just been looking through the Salesforce Spring 21 release notes and I noticed that if you are using a free Gmail account (like me) Salesforce Inbox will stop working on the 31st March. There is no workaround to replace this really useful productivity feature. This is likely to impact only small Salesforce Essentials users (like me).

A G Suite license is £50 per year which is not a killer but it does require a bit of setup (MX records etc) and the migration of emails would be painful. My current thinking is that I am just going to have to let this feature go but if you face this problem and have a different solution let me know.
