No. Sequenzy is for email to people who asked to hear from you: your customers, your product’s users, and people who signed up through a form. Cold outreach and purchased, rented or scraped lists are not allowed, on any plan.

What counts as cold email

A cold email is a first email to someone who does not know you and never opted in to your emails. It does not matter whether the message is B2B, low volume, or personally written. The Terms of Service prohibit:
  • Lists purchased from a third party
  • Lists rented or borrowed from partners or affiliates
  • Addresses scraped or harvested from websites
  • Contest or giveaway lists where email marketing consent was not given
  • Addresses found through append services or email lookup tools

What is allowed

  • People who signed up through your form, landing page or checkout
  • Your customers and the users of your product
  • Contacts you collected in person who agreed to receive email
  • A list you are moving from another email platform, where those contacts already opted in
An old list of real customers is allowed, but verify it first. Addresses that have not been mailed in a long time bounce often, and a high bounce rate pauses sending.

What happens if you import one anyway

The CSV import asks Where did these contacts come from? If you choose Purchased, rented, or scraped list, the import is not refused, but those contacts are held:
  • A campaign that includes them goes to manual review before it sends.
  • A sequence email to one of them pauses that enrollment.
  • A contact is released when they confirm through a signup form or double opt-in, or when our team approves the list.
Sending to people who did not opt in also shows up as bounces and spam complaints, which pause the workspace. See Sender Health for the thresholds.

If your case is unusual

Message support before you import and describe where the contacts came from, how they agreed to hear from you, and what you plan to send. It is faster than waiting for a campaign review.
