Switching from Smartlead to Instantly
There’s no native import tool between Smartlead and Instantly – moving over means exporting your lead lists as CSV and manually rebuilding every sequence step inside Instantly’s campaign builder.
Quick verdict: Worth it if you specifically want Instantly’s unified inbox and its built-in lead database add-on, but expect a full manual sequence rebuild and a fresh mailbox warm-up period regardless of which cold-email tool you’re coming from.
Why teams switch from Smartlead to Instantly
Different unibox and inbox rotation approach
Instantly’s unified inbox (Unibox) and its native lead database are frequently cited reasons teams switch, since Smartlead handles inbox management and lead sourcing somewhat differently.
Bundled pricing tiers with included leads
Instantly’s higher plans bundle a set number of monthly lead credits alongside sending volume, which can simplify budgeting versus paying for lead sourcing separately.
Preference on deliverability tooling
Some teams find Instantly’s warmup network and deliverability dashboards easier to interpret day-to-day, though both tools offer built-in warmup.

How to migrate your data
Every cold-email-to-cold-email migration in this space follows the same manual pattern, since no vendor here offers a named competitor importer.
Step
What happens
1Export your lead lists from Smartlead
Download your active lead lists as CSV files, including current sequence status so you know who’s mid-sequence.
2Clean and segment the export
Remove unsubscribes, bounces, and replied leads before re-uploading, so you don’t accidentally re-contact people who opted out.
3Upload lists as new campaigns in Instantly
Create new lead lists in Instantly and import your cleaned CSVs, mapping custom fields as needed.
4Manually rebuild each sequence step
Recreate your Smartlead sequences – subject lines, body copy, delays, and A/B variants – step-by-step inside Instantly’s campaign builder, since none of this transfers automatically.
5Connect and verify sending mailboxes
Add your sending mailboxes to Instantly and confirm SPF, DKIM, and DMARC records are correctly set up before sending any volume.
6Re-warm your mailboxes before scaling volume
Run Instantly’s warmup feature for at least one to two weeks before resuming full send volume, since sender reputation earned in Smartlead does not carry over to a new sending infrastructure.
What Instantly’s importer doesn’t handle: Sequences, templates, and mailbox warm-up/sending reputation do not transfer between any cold email tools – every sequence must be manually rebuilt, and every mailbox needs a fresh warm-up period in the new platform.
Pricing during the transition
Both tools price primarily by sending volume and lead capacity rather than by seat, but their tier structures differ.
Neither tool has a permanent free plan – both offer free trials only – and both charge extra for add-ons like lead-finding credits, so compare total cost at your actual send volume rather than headline plan prices (as of September 2026).
Feature-parity checklist
Both are cold-email sending platforms with unlimited mailbox connections and built-in warmup, differing mostly in inbox management and bundled extras.

Is there a native Smartlead-to-Instantly import tool?
No – neither platform offers a named importer for the other; migration is a manual CSV export/import plus sequence rebuild.
Will my Smartlead sequences work in Instantly?
No, you’ll need to manually recreate every sequence step, subject line, and delay timing in Instantly’s campaign builder.
Do I need to re-warm my mailboxes when switching?
Yes – sending reputation and warmup progress are tied to the sending infrastructure and don’t transfer between platforms, so plan for a fresh warmup period.
How long should I run both tools in parallel?
Most teams keep Smartlead running for existing active sequences while building and testing new campaigns in Instantly, cutting over fully once deliverability looks stable, often two to four weeks.
Will switching hurt my deliverability?
There’s some risk any time you change sending infrastructure – a gradual mailbox warmup and conservative initial send volume in Instantly reduces that risk.
