Does switching change anything in Instantly?

No. ManyPI only reads your Instantly account and never changes it. What you paste is encrypted, and deleted when the import ends.

Will my campaigns start sending on their own?

No. Every campaign arrives as a paused draft, and nothing sends until you launch it. Replied and opted-out leads are never queued.

Do my merge tags still work?

Yes, the common ones are rewritten for you. {{firstName}} becomes {{first_name}} and {{companyName}} becomes {{company}}. Any other variable becomes a custom field, so {{industry}} turns into {{custom.industry}}. Conditional blocks are removed and their text kept.

Can I import a CSV file instead?

Yes. Export your leads from Instantly and drop the file on Leads in ManyPI. A file brings leads and their columns; campaigns and opt-outs come over only with the key.

Which Instantly API key do I need?

An API V2 key, because V1 keys do not work with V2. Create one under Settings, Integrations, API Keys with the all:read scope.

Which ManyPI plan do I need to switch?

Any plan can run the switch. A workspace holds up to 250 imported leads on Free, 2,500 on Starter, 50,000 on Pro and 250,000 on Business. Custom fields need Starter, A/B variants need Pro, and sending needs a paid plan.

How many leads can one import bring?

Up to 100,000 per run, within your plan's lead limit. Run it again for the rest: an import picks up where it stopped, and leads already in ManyPI are merged, not added twice.

Does switching use my email checks?

No. Leads are queued into the new campaign without an email check, so the switch spends none. Your do-not-contact list is still checked when each email goes out.

Do I have to warm up my inboxes again?

No. An inbox that's already warm can turn the ramp off or set its own numbers.
