How to Switch from Lemlist to BILT AI

Updated June 17, 2026

To switch from Lemlist to BILT AI: export your leads, campaigns, and personalization content to CSV; map Lemlist's multichannel sequences to BILT campaigns; reconnect your sending identities in BILT (SPF/DKIM/DMARC); import a test batch first; rebuild your sequences and turn on SMS and AI reply-handling that books meetings; and run both in parallel for about a week before cutting over.

Lemlist made its name on personalization — custom images, dynamic landing pages, and multichannel touches that make cold email feel one-to-one. That craft is genuinely good at getting the open and the first reply. Where the work continues is after that reply: Lemlist routes the conversation back to a person, and booking the meeting is a manual step. BILT AI consolidates the motion — send, SMS, and AI follow-up that books the meeting — into one engine, so the personalized opener doesn't hand off to a human the moment it lands a reply.

So this migration is about consolidation more than replacement: keeping the multichannel, personalized outreach Lemlist does well while folding the SMS and the AI booking layer into the same tool. Here's how to move your campaigns cleanly and close that handoff gap.

The migration, step by step

  1. Export leads and campaigns to CSVPull your lead lists, campaign content, and personalization assets out of Lemlist to CSV, and keep an untouched backup copy as your rollback.
  2. Inventory multichannel sequencesList every active Lemlist campaign, its sequence steps, and the channels each uses (email, LinkedIn touches, etc.) so you know exactly what to rebuild in BILT before you turn anything off.
  3. Map sequences to BILT campaignsMap your Lemlist sequences, personalization fields, and channel steps onto BILT campaigns and its pipeline. Decide the mapping on paper before importing so step logic and lead data land correctly.
  4. Reconnect sending identitiesSet up your sending domains and inboxes in BILT with proper email authentication (SPF/DKIM/DMARC), re-warm any new inboxes before volume sending, and send yourself a test to confirm deliverability.
  5. Import a test batchImport 25–50 leads into BILT first and verify lead fields, campaign assignment, and personalization fields all landed correctly before the full load.
  6. Import the full datasetOnce the test batch checks out, import your complete lead and campaign data into BILT.
  7. Consolidate SMS and AI bookingTurn on the layer Lemlist leaves to manual work: SMS as a channel and BILT's AI follow-up that works replies in minutes and books the meeting — before disabling anything in Lemlist.
  8. Run both in parallelKeep Lemlist live for about a week alongside BILT so in-flight personalized conversations have a safety net during the transition.
  9. Cut over and archiveOnce BILT is sending cleanly and AI follow-up is booking from replies, cut over fully and archive (don't delete) your Lemlist account.

Consolidation math

Lemlist personalizes the opener across channels; the booking still happens by hand, and SMS and an AI scheduler usually live in separate tools. BILT consolidates the send, the SMS, and the AI booking into one engine. The case isn't that Lemlist's personalization is lacking — it's a strength — it's that the personalized reply hands off to a stack of other tools, and folding that into BILT keeps the whole motion, opener to booked meeting, in one place.

Frequently asked

Will I lose Lemlist's personalization moving to BILT?

The personalized content and field logic carry over — export your campaign content and personalization fields to CSV and map them into BILT campaigns. What changes is what happens after the reply: instead of handing a personalized response to a person, BILT's AI follow-up works it and books the meeting. You keep the craft and add the engine behind it.

How is BILT AI different from Lemlist?

Lemlist is strongest at multichannel personalization that earns the open and first reply. BILT consolidates the full motion — send, SMS, and AI follow-up that books meetings — into one engine. If your personalized outreach lands replies but the booking is a manual handoff across separate tools, that consolidation is the difference.

Does BILT replace my SMS and scheduling tools too?

That's the point of consolidating. Lemlist focuses on email and multichannel touches; teams add a separate SMS tool and scheduler around it. BILT runs SMS and AI booking in the same engine as the send, so the personalized reply turns into a meeting without bouncing between tools.

Will I lose my campaign data?

Not if you export everything to CSV first and import a test batch before the full load. Lead lists and campaign content move cleanly. The real risk is active personalized conversations — protect those by rebuilding sequences in BILT before disabling Lemlist and running both in parallel for about a week.

The takeaway

Switching from Lemlist to BILT AI is a consolidation play. Lemlist personalizes the opener well; the booking and the SMS live in separate tools. Export your campaigns and personalization, reconnect your sending identities, test-import, then fold SMS and AI booking into the same engine so a personalized reply becomes a booked meeting without a manual handoff. Parallel-run for a week, then cut over — one engine from personalized opener to booked call.

Make the switch.

Bring your data; BILT brings the engine — LOIs, cold email, SMS, and AI follow-up working from one pipeline.
