Quick Answers

What tools do you need?

Just the platform account.

How much does it cost?

No paid tools needed: this case uses only the platform itself, which is free to join.

Is it allowed?

Follow the platform rules and disclose ads.

Watch out: Self-reported, and very young. Cold email is regulated (GDPR in Europe, CAN-SPAM in the US): only email people you are allowed to, and honour opt-outs.

Try It Yourself
