Will my columns map on their own?

Most do. ManyPI matches columns by header and by what's in them, and flags anything unsure as “needs a look”. First and last name are merged into one name.

What if a lead is already in ManyPI?

It's merged, not added twice. ManyPI matches on email, or on domain plus name or company, and by default only fills in what's blank.

How do I email these leads?

Connect an inbox and build a sequence in ManyPI. A sequence holds up to 10 emails with waits of up to 90 days, and stops when someone replies. Sending needs a paid plan.

Which files can I import?

CSV, TSV, TXT, JSON and Excel (.xlsx, .xlsm), up to 25 MB. Each import uses the first 10,000 rows, so split a bigger export. Save an old .xls file as .xlsx first.

Which ManyPI plan do I need to import?

Any plan can import a file. A workspace holds up to 250 imported leads on Free, 2,500 on Starter, 50,000 on Pro and 250,000 on Business. Custom columns need Starter, and sending needs a paid plan.

How do I bring my do-not-contact list?

Paste the addresses under Do not contact, up to 5,000 at a time, one per line or comma separated. Anyone who unsubscribes from a ManyPI email is added on their own.

Do my inboxes need warming up first?

Only if they're new to cold email. An inbox that's already warm can turn the ramp off or set its own numbers.

What happens to my data if I leave ManyPI?

It stays yours. Export your leads as a CSV whenever you like, and cancel in settings with no lock-in: you keep access until the end of the billing period.
