Frequently asked questions

Can't find the answer you're looking for? Reach out to our customer support team.

Does Instantly verify emails?
Instantly does not include built-in email verification. You need a dedicated verification tool like Truelist to validate your leads before launching campaigns.
How do I export leads from Instantly?
Open the Leads section in your Instantly dashboard, select the list you want to verify, and click Export to download a CSV file.
Why do bounces matter in Instantly?
Instantly connects multiple sending accounts to scale outreach. High bounce rates from unverified lists can damage the reputation of every connected account, reducing deliverability across all campaigns.
How often should I verify my Instantly lead lists?
Verify every list before importing it into Instantly. If leads sit unused for more than 30 days, re-verify before sending since email addresses go stale quickly.
