SalesBlastBen warns that Cheap Inboxes sees 90% GTM-engineer signups and 10% first-timers, and argues firms should stop sending cold email from HubSpot, Salesloft, or Outreach. He provides a 10-step cold-email playbook: use Instantly, start with 100 inboxes, warm them 2–3 weeks, integrate sequencer+CRM, segment accounts, send 20–30/day per inbox, and centralize replies.

Why it matters

90% of Cheap Inboxes signups are GTM engineers; the other 10% are cold-email first-timers — @SalesBlastBen insists companies must not let sales teams send cold email from HubSpot, Salesloft, Outreach or other 'dinosaur' systems.

Nothing bothers me more than this.

If you have a sales team, do NOT let them send cold emails from HubSpot, Salesloft, Outreach, or any other dinosaur system.

Even if you purchase 1000+ inboxes from us, those outdated tools can't do anything with them.

If that's you, the 10%, here's a crash course on cold email mastery:

1. Get an Instantly account for sending

2. Start with 100 inboxes from Cheap Inboxes

3. Warm them in Instantly for 2-3 weeks

4. Integrate your sequencer with your CRM

5. Build an account list (the bigger, the better)

6. Find 2-3 leads per account

7. Segment the list based on persona, buying triggers, etc.

8. Create custom messaging for each segmented list

9. Send 20-30 emails/day per inbox

10. Have ONE person manage replies
