Short answer: no. Buying or renting an email list is one of the fastest ways to wreck your sender reputation, get blacklisted, and have your Mailpro account suspended.
Why bought lists fail
- No real consent. The recipients never agreed to hear from you — sellers re-package contacts harvested from random sources
- High complaint rates. “Mark as spam” clicks pile up fast and damage your deliverability
- Spam traps. Old or fake addresses on bought lists trigger blacklists on first send
- Legal exposure. GDPR, CAN-SPAM, CASL and most national laws require explicit, demonstrable consent
- Bad ROI. Even if a percentage opens, the brand damage from being labelled a spammer outweighs the gain
What we ask if a complaint comes in
If a recipient complains, our compliance team requests proof of consent within 48 hours. Acceptable evidence includes the date and time the contact opted in, the explicit consent text, proof of an existing customer relationship, or any other documentation showing lawful collection. Bought-list contacts cannot meet this bar.
Build the list the right way
- Use double opt-in on every signup form — you get a verifiable consent trail
- Run lead-magnet campaigns (guides, templates, calculators) that attract motivated subscribers
- Add unobtrusive newsletter prompts on high-traffic pages
- Promote the signup on social channels and in your customer support flows
- Follow the 10 email marketing rules to keep complaint rates low
Already inherited a list you’re unsure about?
If you took over a list from a previous owner or merged with another company, send a re-permission campaign first — ask each contact to re-opt-in, and only mail those who confirm. This rebuilds a defensible consent record.
Grow a clean list instead
A small opt-in list always outperforms a large bought one. Set up double opt-in on your signup form and follow our marketing rules — you’ll see better deliverability and revenue.
