Common questions
- How do I export my leads from lemlist?
- In lemlist, go to Campaigns and open the campaign. Open the Leads list tab, and apply Filters if you need a subset. Tick the top checkbox to select every lead shown, or tick individual leads. Click Export as .CSV in the bulk actions bar. The top checkbox selects only the leads currently shown, so check the count before exporting.
- Do I need to change the lemlist CSV before uploading it?
- No. The email column is found by its header or its contents, so the lemlist export works as it is. Every other column is kept, and the cleaned files come back with your original columns so you can import them straight back into lemlist.
- Why verify a list that came from lemlist?
- Lead databases go stale as people change jobs, and a bounced cold email counts against your sending domain the same as any other. Verifying the lemlist export before it goes into a sequence keeps the bounce rate under the roughly 2% line where mailbox providers start filtering, and it catches catch-all domains you should not send to blind.
- How much does it cost?
- Verification is $39 a month with no limit on verifications, for files up to 100,000 rows. See the pricing page for the plans.
