How to move away from Big Tech Email Providers

Here's a guide on how to easily get away from Gmail.

Most providers offer step-by-step migration tools to transfer your emails, contacts, and calendars seamlessly. Once you’ve chosen a new provider, update your email address with important contacts and services, and carefully consider setting up automatic forwarding from your old account during the transition. It might make the transition process smoother, but it also scrutinizes your privacy by sharing your new contact with a Big Tech service.
