The honest part
Skip Ballast if this is you
You have no list or offer yet
A sending tool won't find you customers. Work out who you're writing to and why they'd reply, then come back.
You want to blast a bought consumer list
Our acceptable use policy forbids it and the breakers would pause you anyway.
You send newsletters or receipts
Use an email service built for that. Ballast is for one-to-one outbound from your own mailboxes.
You want guaranteed inbox placement
Nobody can sell that honestly. We keep you inside the published rules and stop before a bad day burns a domain.
Bring your mailboxes. Keep your domains.
Import from Instantly, Smartlead, Lemlist, Apollo or Clay. Every feature on every plan, from $19 a month.
