The Questions To Ask Before Choosing Mailforge

Domain architecture
Ask how many domains are created for your target volume
Tracking domains
Ask whether custom tracking domains are configured per client or globally
Automation access
Ask whether API/CLI access matters for your workflow or is just nice to have
Replacement policy
Ask what mailbox replacement SLA exists
Domain architecture
Ask how they prevent overloading new domains
When Switching Away From Mailforge Is A Bad Idea
Avoid choosing Mailforge just because of low unit cost if you have not mapped domains, inboxes, and daily send limits.
Client isolation
Fast setup can still create messy domain architecture if no one plans client separation
Tracking domains
Changing provider can break custom tracking domains and sequencer connections
True cost
Low per mailbox cost is irrelevant if accounts are pushed too hard

How many inboxes do I need?
