The StackPricing Value Awards
Most software awards are pay-to-play. These aren't. Every winner below is computed from our verified pricing data (July 2026) — the same numbers that power our calculators. Several winners have no affiliate program at all, and affiliate relationships never influence results.
Newsletter & email tools
The lowest-priced paid option at every list size from 5,000 to 100,000 subscribers — $40/mo at 10k where the category average is $91/mo.
Free to 2,500 subscribers — the joint-largest free tier we track — with real newsletter features (growth tools, referrals) rather than a stripped demo.
The cheapest paid plan under 2,500 subscribers ($13/mo at 1k, billed annually) with automation included.
The cheapest full-featured platform at 25,000+ subscribers — $114/mo at 25k and $163/mo at 50k, billed annually.
Transactional email / SMTP
At $0.10 per 1,000 emails, it is cheaper by an order of magnitude at every volume — $100/mo for a million emails where premium senders charge $350–1,800.
The most generous free sending allowance we track: 300 emails/day (~9,000/month) with no expiry.
Editorial pick: the cleanest API and docs of the senders we compare, React-based email templates, and a free 3,000/month tier to build on.
SMS marketing
The cheapest way for developers to send at low volume — $13/mo for 1,000 texts with estimated carrier fees included — and the base rate most SMS platforms build on.
The cheapest option overall at 2,500+ texts/month once carrier fees are counted — $90/mo at 10,000 texts, fees included — with campaigns, flows and compliance handled inside Klaviyo.
The cheapest dedicated SMS-marketing platform at most volumes we track — $49/mo at 1,000 texts and $899/mo at 50,000, with the lowest annual entry price ($25/mo).
How winners are decided
Price-based awards are computed directly from our dataset — the cheapest qualifying plan at the stated list sizes or send volumes, billed annually where available. Where a judgment call is involved (e.g. “full-featured” or developer experience), the award is marked as an editorial pick and the criteria are stated. Full details in our methodology. Winners may display the badge free of charge; the badge must link back to this page.
