Some links on Email Stack Guide may be affiliate links. If you sign up for or buy a tool through one of them, we may earn a commission from the vendor. Where a link is an affiliate link, we say so near the link.

Right now we are still setting up partner programmes. We only add an affiliate link after a vendor has approved us.

What that means

• We aim for clear, sourced comparisons and pricing notes.
• Commissions can create an incentive to feature partner tools; we still mark uncertain prices and avoid inventing quotes.
• “Best” or “recommended” means a fit for a described use case, not a guarantee of results, deliverability, or earnings.
• Some tools are covered editorially only (no affiliate link) when no suitable programme exists yet.

Before you buy

Check the vendor’s current pricing, terms, and limits on their site. Vendors change plans often; we check our figures against the vendor’s own pages on the day we publish or update a page.
