How we ranked these

• Candidates. Every tool we hand-flagged as a Mailtrap alternative, plus every tool sharing its primary category (deliverability). Tools we don't yet track are not listed; we never link out to a tool we haven't verified.
• Order. Free-plan tools first, then ascending by entry monthly price (the headline anchor we capture from each vendor). Custom-priced tools sort last. Ties broken alphabetically.
• Tags. Each row's tags are computed against Mailtrap's data: cheaper entry, free plan present, more plan tiers, enterprise tier present. No editorial "better than" claims.
• Freshness. Pricing is captured weekly from each vendor's pricing page, listed in the source citation below. Confirm at the vendor's page before buying.
