How to Switch From Outplay to lemlist Without Losing Data or Campaigns

Why teams switch from Outplay to lemlist

Switching from one sales engagement platform to another comes down to hitting a ceiling. If you’re reading this, you’ve probably already felt it: Outplay works for email sequences, but the moment you want to coordinate across more channels or consolidate your prospecting, enrichment, and deliverability into one workflow, you’re bolting on third-party tools to fill the gaps.

Outplay’s multichannel sequencing across email, calls, and LinkedIn works for day-to-day SDR outreach, but teams that scale past basic sequences often run into friction. Here’s where lemlist differs in practice:

• •

  Multichannel coverage in one campaign: lemlist lets you build your workflow with steps such as emails, LinkedIn messages, calls, tasks, and delays, plus SMS and WhatsApp, all inside a single sequence (see how to create a lemlist campaign).

• •

  Built-in lead database and enrichment: lemlist includes a 600M+ contact database with waterfall enrichment across 14+ data providers. Outplay requires external tools for comparable coverage.

• •

  Deliverability infrastructure: lemwarm, lemlist’s built-in warm-up and deliverability booster, comes with every lemlist seat. Outplay doesn’t include a native warm-up tool.

• •

  AI personalization and intent signals: lemlist’s AI agents research leads, detect buying signals, and generate personalized outreach variables. In Outplay, that work is manual or requires separate integrations.

4 risks that kill sales engagement migrations (and how to prevent each)

Before touching any export button, it helps to know exactly what can go wrong. Every platform migration carries the same four predictable failure points.

Active sequence disruption

If you hard-stop Outplay before lemlist is ready, prospects who are mid-sequence (meaning they’ve received some but not all steps in your outreach sequence) go silent. A lead who was about to get a follow-up tomorrow suddenly receives nothing.

The fix: don’t shut off Outplay until lemlist is running and tested. Plan a one-week overlap where both tools operate simultaneously.

Prospect and engagement data loss

All your engagement history, including opens, clicks, replies, and bounces, lives inside Outplay. You can export a CSV file of your prospects, including their stage, status and response data, from the Prospects screen. However, if you cancel your Outplay account before exporting, that data is gone.

Sending domain reputation damage

Connecting your mailboxes to a new platform and immediately sending at full volume triggers spam filters. Reputation is tied to your sending behavior, not just the tool. Even if you’re using the same email addresses, inbox providers see the shift in patterns.

Rep productivity dip

Your reps will lose time learning a new UI and rebuilding workflows. Budget one to two weeks of reduced output and plan quota expectations around it rather than pretending the transition is instant.

How to export your data from Outplay before switching

This is where the migration actually starts. Every step below is a concrete action, done in order.

1. Export your prospect lists as CSV

In the Outplay Prospects screen, click the arrow next to Add Prospects, click Export Prospects, and Outplay generates a CSV file for your browser to download. Confirm that custom fields (company, title, phone, tags) are included. This CSV becomes your import file for lemlist.

2. Record your sequence templates and step logic

Copy your best-performing sequence structures into a spreadsheet: the number of steps, channel order, delay timing, and conditional branches. Outplay doesn’t export sequence logic as a file, so you’ll capture it manually.

3. Pull engagement history

Export or screenshot engagement data for active sequences. You’ll use reply and bounce data to segment contacts before importing, for example, to exclude bounced emails and flag replied leads as warm.

4. Export your bounce and unsubscribe lists

These are non-negotiable. Importing previously bounced or unsubscribed contacts into lemlist will damage your sender reputation and can violate compliance rules. Filter your Outplay export for bounced and opted-out contacts and save them in a separate file.

5. Sync everything to your CRM first

Outplay’s CRM integration will update your CRM with all your activity related to email, call logs, notes, meeting logs, and more, and will also sync the data of Contacts, Companies, and Deals between the platforms. Make sure that sync is complete before you cancel. Once Outplay access ends, your CRM becomes the only historical record.

How to import Outplay leads and sequences into lemlist

Now that your data is safely exported, here’s how to bring it into lemlist.

1. Upload your prospect CSV and map fields

Go to Campaigns, open the campaign you want to import leads into, click Leads list, then click Import new leads, select CSV import, then click in the upload area or drag and drop your CSV file (see lemlist’s guide on how to import leads from a CSV file). During the setup step, assign each CSV column to the correct lemlist variable type. This is what makes lemlist recognize fields like {{email}} and {{linkedinUrl}} in your campaign steps, as explained in choosing the right CSV import type.

2. Rebuild your top sequences or let lemAgent do it

You have two paths. You can manually recreate your best Outplay sequences using lemlist’s campaign builder, adding email, LinkedIn, call, and SMS steps with delays and conditions. Or you can describe your sequence goals in plain language to lemAgent (lemlist’s AI assistant), and it generates a multichannel campaign structure for you.

Start with the two or four sequences that generate the most replies and meetings. You don’t have to rebuild everything on day one.

3. Enrich imported contacts with verified emails and phone numbers

On the “Enrich leads data” step, choose whether you want lemlist to find/verify emails, find phone numbers, or enrich LinkedIn data, then click Import leads to finish. Outplay data may have stale emails or missing phone numbers. lemlist’s waterfall enrichment queries multiple data providers in sequence and only charges for verified results.

4. Run a test sequence before going live

Send a small batch (50–100 contacts) through your rebuilt sequence first. Check that personalization variables render correctly, links track properly, and emails land in inbox. Fix issues before scaling to your full list.

Outplay features mapped to lemlist equivalents

If you’re used to a specific Outplay workflow, this table shows where to find the equivalent in lemlist:

How to handle prospects who are mid-sequence during the cutover

This is the part most migration guides skip, and it’s usually the part that costs you pipeline.

Flag protected contacts before you pause anything

In Outplay, tag or export every contact currently in an active sequence. Note which step each contact has reached. These leads require special handling during the transition, not a cold restart from step 1.

Run both platforms in parallel for one week

Keep Outplay running for active sequences while you build and test in lemlist. Yes, you’ll pay for both tools for a short window. That’s cheaper than losing pipeline because 200 leads went silent mid-sequence.

Re-enroll remaining contacts within 48 hours

Once the parallel window closes, import mid-sequence contacts into lemlist and place them at the appropriate step. Use your exported engagement data to determine where each contact left off. A lead who already received four emails doesn’t want to start over from your intro message.

How to protect your sending reputation when you move to lemlist

This is the single most overlooked step in any platform migration. A new platform means new sending infrastructure, even if you’re using the same mailboxes. Inbox providers notice the shift.

1. Connect mailboxes in batches

Don’t add all your sending accounts at once. Start with two or four mailboxes, verify they’re configured correctly (SPF, DKIM, DMARC), then add more over the following days.

2. Activate lemwarm on every mailbox immediately

lemwarm helps improve the deliverability of your email address by building sender reputation gradually, making it more likely that your emails land in the inbox instead of spam (see how to connect an email address to lemwarm). Turn it on the moment you connect each mailbox, before you send any campaign emails.

3. Cap daily sending volume for the first two weeks

For a new mailbox the recommended range is 30–40 emails per day (see lemlist’s guide to setting up lemwarm and warming your inbox). Start with low daily send limits and ramp gradually. lemlist’s deliverability setup lets you configure automatic volume caps and time-zone-based sending windows.

4. Monitor inbox placement in the Deliverability Hub

Use lemlist’s inbox placement testing to check whether emails land in primary, promotions, or spam before scaling. Set up alerts for bounce rate spikes so you catch problems early rather than discovering them in your reply rates two weeks later.

How to reconnect your CRM and integrations in lemlist

Your CRM is likely already holding Outplay activity data from the sync you ran before canceling. Now you’ll connect it to lemlist so new activity flows there instead.

• •

  CRM (HubSpot, Salesforce, Pipedrive): Native two-way sync. Activity logs, deal stages, and contact updates flow automatically.

• •

  Slack notifications: Available through integrations to alert reps on replies and engagement.

• •

  Zapier / Make: lemlist supports both for custom automations that replace any Outplay Zaps you were running.

• •

  API and MCP: For teams with custom workflows, lemlist exposes API endpoints and an MCP server for AI agent integration.

If you were using Outplay’s bi-directional sync with Zapier, rebuild equivalent automations in lemlist before you cancel Outplay. Zaps connected to Outplay will stop working the moment your account is deactivated.

Week-by-week migration timeline from Outplay to lemlist

Here’s the schedule that keeps your pipeline intact while you move everything over.

Week 1: Audit and export

Audit active sequences. Flag mid-sequence prospects. Export all CSVs (prospects, bounces, unsubscribes). Sync all activity to your CRM. Cancel nothing yet.

Week 2: Build and test in lemlist

Start a 14-day free trial (no credit card required). Import leads, rebuild or generate your top sequences, connect mailboxes, activate lemwarm, and reconnect your CRM. Run test sequences on small batches.

Week 3: Parallel operations

Let remaining Outplay sequences finish while new campaigns run in lemlist. Monitor deliverability in both tools. Move mid-sequence contacts into lemlist as Outplay sequences complete.

Week 4: Full cutover

Pause all Outplay sequences. Confirm all contacts are active in lemlist. Verify CRM sync is clean. Cancel your Outplay subscription. Archive exported CSVs for reference.

5 migration mistakes that cost you pipeline and how to avoid them

1. Importing bounced or unsubscribed contacts into the new platform

This burns your sender reputation on day one. Always filter these out before uploading to lemlist.

2. Skipping warm-up and sending at full volume immediately

The ramp-up increment for a new mailbox is 1, meaning you add one email per day to your sending volume, as detailed in how to set up and use lemwarm. Sudden spikes get flagged.

3. Rebuilding every sequence instead of prioritizing top performers

Start with the sequences that generate the most replies and meetings. You can rebuild the rest in weeks two and four.

4. Forgetting to update tracking links and custom domains

Old Outplay tracking domains won’t work in lemlist. Set up lemlist’s tracking and custom sending domains before launching campaigns.

5. Not running parallel operations for mid-sequence contacts

Abruptly stopping Outplay leaves active prospects in limbo. Overlap both tools for one week. The cost of a single month’s overlap is far less than the cost of a dead pipeline.

Your outbound gets better after the switch

Switching platforms is a one-time effort. Once it’s done, you have multichannel outreach, built-in enrichment, AI personalization, intent signals, and deliverability tools all in one place. The migration takes real work, but it removes the tool sprawl that was slowing you down in the first place.
