B2B SALES OUTREACH · MIGRATION GUIDE
Switching from Instantly to Smartlead
Switching from Instantly to Smartlead is a fully manual process – export your leads as CSV and rebuild every campaign sequence inside Smartlead, since no native importer exists between the two.
Quick verdict: Makes sense if you specifically want Smartlead’s unlimited contact storage on its top tiers or its more granular conditional branching, but the migration itself carries the same manual rebuild and mailbox re-warming cost as any cold-email tool switch.
Why teams switch from Instantly to Smartlead
Unlimited contact storage on higher tiers
Smartlead’s Unlimited Smart and Unlimited Prime plans remove the contact-storage cap entirely, which can matter for teams managing very large prospect databases.
Sub-sequence and conditional branching
Smartlead’s campaign builder supports more granular conditional branching within a sequence than some teams find in Instantly’s builder.
Included CRM and API access at higher tiers
Smartlead bundles a basic CRM layer and broader API access into its higher plans, which can reduce the need for separate tooling.

How to migrate your data
This follows the same manual pattern as any cold-email-tool migration, since neither vendor offers a competitor importer.
Step
What happens
1Export your lead lists from Instantly
Download your active lead lists and campaign status as CSV from Instantly before starting the move.
2Clean the export
Strip out unsubscribes, bounces, and already-replied leads so you don’t re-contact people who’ve opted out.
3Upload lists into Smartlead
Create new campaigns in Smartlead and import your cleaned CSVs, mapping custom fields as needed.
4Manually rebuild each sequence
Recreate your Instantly campaigns – subject lines, body copy, delay timing, and A/B variants – step-by-step in Smartlead’s sequence builder.
5Connect and verify sending mailboxes
Add your mailboxes to Smartlead and confirm SPF, DKIM, and DMARC records before sending meaningful volume.
6Re-warm mailboxes before scaling
Run Smartlead’s warmup pool for one to two weeks before resuming full send volume, since warmup progress and reputation don’t carry over from Instantly.
What Smartlead’s importer doesn’t handle: Sequences, templates, and mailbox sending reputation do not transfer – every campaign must be manually rebuilt in Smartlead, and every mailbox needs its own fresh warmup period.
Pricing during the transition
Both tools price by sending volume and contact capacity rather than by seat count, with Smartlead offering unlimited contacts at its top tiers.
Neither vendor offers a permanent free plan; compare total monthly cost at your actual sending volume, since both add extra charges for verified-email credits and other add-ons (as of September 2026).
Feature-parity checklist
Both are unlimited-mailbox cold email platforms with built-in warmup; the differences are mostly around contact storage limits and bundled extras.

Is there a native Instantly-to-Smartlead import tool?
No – you’ll export leads as CSV and manually rebuild sequences; neither vendor documents a direct importer for the other.
Will my Instantly campaigns transfer to Smartlead?
No, campaign steps, subject lines, and timing need to be manually recreated inside Smartlead’s sequence builder.
Does my mailbox warmup progress carry over?
No – sending reputation is tied to the platform’s warmup network, so you’ll need to re-warm mailboxes in Smartlead before scaling volume.
Is Smartlead cheaper than Instantly?
At comparable send volumes the two are broadly similar in price, though Smartlead’s top tiers offer unlimited contact storage where Instantly’s plans stay capped.
How risky is this migration for deliverability?
Moderate – any sending-infrastructure change carries some deliverability risk, which a gradual warmup and conservative initial volume in Smartlead helps offset.
