About
Receipts, not reviews.
Outbound Stack Tracker is an independent, sourced record of what cold email tools cost and how they behave.
Funding
How we make money
Affiliate links, a labeled featured-listing slot, and newsletter sponsors. None of them change table order, calculator results or comparisons.
What we track
- List prices and plan limits, from official pricing pages
- Refund and cancellation terms, quoted from vendor terms
- Third-party inbox-placement tests (never vendor claims)
- A dated log of every change
Newsletter
Price changes, before your renewal.
One email a month when Instantly, Smartlead, Apollo, Clay, Lemlist, Reply.io, Saleshandy or Woodpecker change pricing or policies.
