SalesIntel provides human-verified B2B contact data, refreshed every 90 days, which is part of why people keep finding themselves back in it after opting out.
Use their opt-out page and pick "Right to Opt Out / Do Not Sell," or use their separate Do Not Sell My Information form if you specifically want to stop data sales. They aim to delete records within 30 days and add you to a suppression list to stop you being re-added.
Frequently asked questions
Will my data come back?
Possibly. SalesIntel refreshes its data every 90 days, so re-appearance is more likely than with some other providers. The suppression list they add you to helps prevent this, but it is worth checking back periodically.
How long does this take to process?
SalesIntel aims to delete records within 30 days and add you to their suppression list to prevent re-addition.
