The Scalelist Instantly integration sends the leads you find, with verified work emails, straight into an Instantly campaign. You paste an Instantly API key into Scalelist once, then push any list from one menu: pick the campaign and send. lemlist, Smartlead, Woodpecker and Saleshandy connect the same way.
- One key, no CSV: your Instantly campaigns load inside Scalelist, so there is no export and re-upload
- Verified before it leaves: push only Valid emails, and keep Risky (catch-all) addresses for a separate campaign
- 0 credits to push: you pay for data found, 1 credit per email and 20 per mobile, never for the sync

The Instantly integration is a direct sync from a Scalelist list to an Instantly campaign: Scalelist adds the leads you select to the campaign you choose, using an API key from your Instantly workspace. It replaces the export, clean and re-upload loop.
It runs one way, from Scalelist to Instantly. Instantly keeps doing the sending, warmup and replies. Scalelist, an AI lead finder, does the finding and verifies every email before the lead gets there.
How to connect Instantly and send your first list
Connecting Instantly takes one API key and one menu. These five steps take you from an empty campaign to leads loaded.
1. Create an Instantly API v2 key
In Instantly, open Settings, then Integrations, then API Keys, and create an API v2 key. Instantly asks you to choose scopes: Scalelist lists your campaigns and adds leads to them, so give the key read access to campaigns and create access to leads. Copy the key right away; Instantly shows it only once.
2. Paste the key into Scalelist
In the Scalelist app, open Integrations, choose Instantly and paste the key into the connect dialog. The dialog links straight to the Instantly page from step 1. When the card shows Connected, you are done; disconnect from the same card at any time.
3. Build the list and find the emails
Describe your buyer in one sentence in the Scalelist Lead Finder, or open a list you imported, and find the emails. Every email is verified before it is returned and labelled Valid or Risky.
4. Push the leads to a campaign
On the list, open Push Leads and choose Push Valid Emails Only, Push Selected or Push All Leads. Pick Instantly, pick the campaign, then click Send to Instantly.
5. Check the first lead in Instantly
A progress bar on the list shows the sync. Open one lead in the Instantly campaign and check which fields arrived before you write merge tags or launch.
Instantly integration details: syncs, mapping, verification and credits
These four details decide whether the first send goes well. The same four apply, with small differences, to the other sequencers further down.
What syncs
Leads with an email go into the Instantly campaign you picked. Leads with no email are skipped, and the dialog counts them before you send, for example 3 skipped and 47 sent. If you cancel a sync halfway, the leads already synced stay in Instantly.
Field mapping
There is no field-mapping screen for Instantly; the mapping screen in Scalelist is for HubSpot. Scalelist sends each lead with its email, and which other fields arrive is not documented yet. Check one synced lead before you use first name, company or title as merge tags.
Verification before sending
Push only Valid emails to a campaign that sends from your main domain. Risky means the domain accepts every address (a catch-all), so the mailbox cannot be confirmed; Scalelist’s help center puts the deliverable share at about 20 to 30%.
- Valid: use Push Valid Emails Only, into your main campaign.
- Risky: select the Risky rows and use Push Selected into a separate campaign on a secondary domain, in smaller batches. Our guide to catch-all emails explains why.
- Not found: the push skips them. If they matter, call them instead: the mobile number API and the in-app Mobile Finder cost 20 credits per mobile found.
Verification protects the list; your domain setup protects the sender. Run through our email deliverability best practices before the first campaign.
Credit costs
Connecting and pushing cost nothing. You pay only when Scalelist finds data.
| Action | Credits |
|---|---|
| Connect Instantly, push a list | 0 |
| Lead found in Lead Finder | 1 |
| Email found (Valid or Risky) | 1 |
| Mobile found | 20 |
| Nothing found | 0 |
A 200-person Lead Finder list with 180 emails found costs 380 credits. Pushing it to Instantly costs 0. What Instantly itself charges is covered in Instantly pricing.
lemlist, Smartlead, Woodpecker and Saleshandy integrations
The other four sequencers connect and push exactly like Instantly. The differences are where the key comes from, what you pick when you push, and what happens to contacts with no email.
| Sequencer | Connect with | You push into | Contacts with no email | On the sequencer’s side |
|---|---|---|---|---|
| Instantly | API v2 key | A campaign | Skipped | Scoped key, shown once |
| lemlist | lemlist API key | A campaign | Still sent | API listed on the Email plan |
| Smartlead | Smartlead API key | A campaign | Skipped | API from the Pro plan |
| Woodpecker | Woodpecker API key | A campaign | Skipped | API listed as an add-on |
| Saleshandy | Saleshandy API key | A sequence, then a step | Skipped | API limits published for all plans |
lemlist integration
- What syncs: the leads you push, into the lemlist campaign you pick. Contacts with no email are still sent, because lemlist campaigns can include non-email steps.

- Verification before sending: Push Valid Emails Only for email steps; Risky rows go to a separate campaign.
- Credit costs: 0 to push. 1 per email found, 20 per mobile found.
Smartlead integration
- What syncs: leads with an email, into the Smartlead campaign you pick. Contacts with no email are skipped and counted.

- Verification before sending: same rule: Valid to the main campaign, Risky to a separate one.

Direct sync, API or CRM first: which route fits?
The direct sync fits when your leads start in Scalelist. Pick another route when they start somewhere else.
- Leads start in Scalelist: use the direct sync on this page.
- Leads start in a form, a CRM or your own app: call the Scalelist API and add the lead to your sequencer from code. Ready-made flows are in our lead enrichment automation recipes.
- Leads live in Clay: enrich rows through the API with an HTTP column; see the Clay API guide.
- Your team works from HubSpot: push to HubSpot first with the HubSpot integration, then enroll from there.
- Still choosing a sequencer: compare them in our roundup of the best sales engagement platforms.
Pricing
The sequencer syncs cost no credits. You pay for what Scalelist finds: 1 credit per lead or email found, 20 per mobile found, 0 on a miss. Plans run from 29 USD for 500 credits to 649 USD for 20,000, with no per-seat price and no annual contract. See every Scalelist plan, or browse every connector on the integrations page.

Does Scalelist have an Instantly integration?
Yes. Scalelist syncs directly with Instantly: you connect an Instantly API v2 key once, then push leads from any Scalelist list into the Instantly campaign you choose. The same direct sync exists for lemlist, Smartlead, Woodpecker and Saleshandy. HubSpot is the one native CRM connection.
How do I connect Scalelist to Instantly?
Create an API v2 key in Instantly under Settings, Integrations, API Keys, with read access to campaigns and create access to leads. In the Scalelist app, open Integrations, choose Instantly and paste the key. Once the card shows Connected, open a list, use Push Leads, pick your campaign and send.
Does sending leads to Instantly cost credits?
No. Connecting Instantly and pushing leads cost 0 credits. You pay when Scalelist finds data: 1 credit per lead found in Lead Finder, 1 per email found (Valid or Risky) and 20 per mobile found. A lookup that finds nothing costs 0.
Can I send only verified emails to Instantly?
Yes. Use Push Valid Emails Only, and only addresses whose mailbox was verified go to the campaign. Risky emails come from catch-all domains, so they cannot be confirmed; about 20 to 30% of them are deliverable. Push those separately into a campaign on a secondary domain.
What happens to leads without an email?
Instantly, Smartlead, Woodpecker and Saleshandy only receive leads that have an email. The push dialog counts the ones it will skip before you send. lemlist is the exception: contacts without an email are still sent, because lemlist campaigns can include steps that do not need one.
Can I map Scalelist fields to Instantly custom fields?
Not yet. Scalelist has a field-mapping screen for HubSpot, but none for Instantly or the other sequencers, and the list of fields sent is not documented. Push one lead first, check which fields arrived in Instantly, and build your merge tags on those.
