I’ve been experimenting with CRM software, as much to help manage my personal life and friendship groups as my work. Cloze seems the best option I’ve found so far. Unfortunately, it’s a fairly expensive proposition for something that won’t actively generate me money. HubSpot CRM is free, but the product itself seems pretty average. You get what you pay for, I suppose.
When I start looking around the web for software, I also get a bit disappointed that I chose to go with Fastmail for my email service. While all these CRM services have native integrations for GSuite and O365, poor standards-compliant Fastmail gets left behind. I’ve been able to get IMAP email to work, but not contacts and calendars.
