Email campaign crashed after I switched to a new platform

Migrated our nurture sequence to a cheaper tool last Tuesday. Lost all our custom fields in the transfer. 1,200 contacts got the wrong messaging for three days before I noticed. Spent a full weekend rebuilding the flows and sending apology emails. Anyone else had a migration go sideways like this, or did I just pick the wrong vendor?

Lost three days of email data to a similar situation once. The new tool's import wizard just silently dropped fields like a clumsy waiter. Ended up writing a script to pull everything from backups, but the damage was done. Migration checklists are now my religion.
