One price,
however big your list
Most email tools charge more as your list grows. Mailbo doesn't count contacts, so the price is the same at every size.

Questions
before you switch
Moving a list is a big step. Here is what people ask first.
Talk to usIs it really unlimited?
Yes. Contacts, campaigns, sends and automations are never capped or metered, on any plan.
Can I bring my list from another tool?
Import a CSV with tags and custom fields. Lists, tags and segments are ready the same day.
Are A/B tests and drip sequences extra?
No. Both come with every plan, along with advanced filtering.
How do I keep my list healthy?
The dashboard flags inactive contacts and unsubscribes, so you can clean up before inbox placement drops.
