How to Migrate Away from ProtonMail

The first move in any change to ProtonMail is the least exciting one: make a complete copy of your data and put it somewhere the product cannot touch. Frustration is exactly the state in which people skip this step, and it is the step that decides whether a migration gone sideways costs you an afternoon or costs you the work itself. Independent copy first, everything else second.

Formats decide the difficulty of everything downstream, so find out what ProtonMail will hand back before you plan any of the rest. Do it while the account is fully alive, cancellation frequently closes the door on your own data, and read the product's own export or data-download documentation rather than assuming. Where you are offered a choice, take the most open, widely readable format on the list; a file only the old tool understands is an export in name only.

The useful way to shortlist against ProtonMail runs backwards from the obvious one: name the single thing you cannot give up before you open any list of rivals, then hold every other email providers option against that one line. ProtonMail concentrates on encrypted-email and privacy, so a genuine alternative either serves that same need more precisely or covers ground ProtonMail leaves open. Research two candidates properly rather than skimming eight, because a shortlist you have actually tested beats a long list you only read about. Our comparison pages cover named email providers rivals in more detail when you reach that stage.

First attempts at moving data into a email providers tool almost never land clean, and that is fine as long as you find out on a sample rather than on the full set. Bring a representative handful across, open it, and check the structure held: fields where you expect them, nothing silently truncated or misfiled. A second pass over a small test batch costs minutes; repairing a mapping mistake across the entire collection costs far more.

Closing the ProtonMail account is the last step, not a formality, so earn it with evidence: the counts on both sides agree, the specific items you rely on open cleanly in the new tool, and a spot check turns up nothing that vanished in transit. Until the replacement has carried genuine work long enough to earn your trust, leave the old account standing, downgraded is fine, gone is premature.
