lemlist campaigns
Clean the lemlist list before the campaign
lemlist is built for personalized outbound. Hard bounces still tax your domains and warmup. Verify every lead with Verifly before import or before the first send so undeliverable, disposable, and role addresses never hit the campaign. Prepaid credits, no monthly verifier seat.

Built for lemlist email verification
Use Verifly when you need a simple API, predictable pricing, and clean JSON results before emails hit your product, CRM, or campaign tool.
Where Verifly sits before lemlist
Typical path: scrape or enrich leads → Verifly verify → keep deliverable → create lemlist campaign / add leads → personalize and send. Skipping verify means lemlist burns sending capacity on addresses that will hard-bounce on first touch.
Verifly returns deliverable / undeliverable / risky plus disposable, role, and catch-all flags. Filter those before import. Credits from $2/1k to $0.60/1k, never expire.
Wire list clean into your lemlist prep
Export or stage your campaign list. Call GET /api/v1/verify per row or POST /api/v1/verify/batch for chunks. Import only deliverable (and optionally risky) into lemlist. For recurring agency flows, use n8n/Make to verify then call the lemlist API.
- Mint a free Verifly API key (vf_…) — trial credits included.
- Stage campaign emails in CSV, Clay, Sheets, or an automation.
- Verify; drop undeliverable, disposable, and (usually) role accounts.
- Import survivors into lemlist; launch campaign on a warmed domain.

Campaign volume is bursty: one client launches 30k leads this week, next week is quiet. Monthly verifier seats bill the quiet weeks. Verifly prepaid packs sit ready until the next launch.

FAQ
Frequently asked questions
Does Verifly integrate natively inside lemlist?
Use CSV pre-clean or an automation (n8n/Make/Clay) that verifies then creates leads via the lemlist API. Same Bearer vf_ key as every other Verifly integration. See /lemlist-email-verification.
Should I verify after enrichment or after personalization?
Before import / before first send. Personalization tokens do not fix undeliverable mailboxes. Verify as soon as you have an email column.
What about catch-all domains on lemlist campaigns?
On a fresh domain, exclude catch-all and risky. On warmed inboxes you can keep a controlled share and monitor bounce rate. Verifly flags them explicitly.
How does this compare to Instantly / Smartlead workflows?
Same pattern: verify before sequence. See /use-cases/instantly-smartlead for the sequencer-specific angle; lemlist follows the same list-hygiene rule.
Is there a free way to test?
New accounts get free trial credits. Verify a 20–50 row sample from your next lemlist campaign, confirm results, then buy a pack.
