A nonprofit's budget is the whole story, and its list is mostly non-paying supporters, so we weight the real price after any nonprofit discount and how many contacts you can hold for free. GetResponse wins on the deepest standing discount in the category — 50% off every plan for verified NGOs. Brevo and Kit cost a small org nothing. Constant Contact wears the nonprofit halo, but its real discount demands a year's prepay, and Klaviyo's profile billing is built for stores, not donors.
A nonprofit pays from a constrained budget and emails a list of supporters who rarely transact, so we weighted cost after the nonprofit discount and free-tier contact limits above advanced automation and design. The platform that gives the deepest standing discount with no upfront prepay wins; a discount you must finance a year ahead is not a discount. See the full rubric →

The deepest no-strings discount in the category: 50% off every plan for verified NGOs, confirmed June 2026. That turns the $19 Starter into $9.50/mo for 1,000 contacts with autoresponders, landing pages and 24/7 chat, and the 10,000-contact tier into roughly $40. Nothing else pairs a full feature set with a permanent half-price rate.
For a small org the cheapest answer is free: 300 sends a day and unlimited stored contacts, billed by emails sent rather than supporters held. When you outgrow it, Starter is $9/mo for 5,000 emails. Plainer templates and a thin nonprofit story, but unbeatable on cost for a volunteer-run list.
Free to 10,000 subscribers with unlimited broadcasts — the most generous subscriber ceiling for a growing supporter list. Tag-based segmentation handles donors, volunteers and event lists cleanly. You only pay ($39/mo at 1,000) for automations and RSS, which many small nonprofits never need.
The familiar choice, but the discount is the category's shallowest — 15%, applied only after you request it with 501(c)(3) documents — and it still bills by contact count. Standard's $20/mo at 500 contacts becomes $100/mo at 5,000 before the cut. Your supporter list is the meter.
Long marketed to nonprofits, but read the fine print. The headline 30% discount requires a 12-month prepay — cash a nonprofit rarely has free — and the deeper 50% rate runs through TechSoup eligibility. Base prices are the category's highest, topping out at $80/mo Premium. A discount you must finance is not cheap.
Built around store orders and billed on active profiles, with no nonprofit discount. A donor list generates none of the ecommerce signals Klaviyo monetizes, so a nonprofit pays full retail for an engine it cannot feed. Wrong economics for fundraising.
GetResponse after its 50% NGO discount — about $9.50/mo for 1,000 contacts with full features. For a tiny org, Brevo (unlimited contacts, 300 sends/day) and Kit (free to 10,000) cost nothing.
Is the Constant Contact nonprofit discount worth it?
Only if you can prepay. The 30% rate requires 12 months upfront and the 50% rate runs through TechSoup eligibility. Its base prices are the highest here, so the effective cost is rarely the bargain it appears.
Does Mailchimp give nonprofits a discount?
Yes, 15%, applied after you request it with 501(c)(3) documentation — and it still bills by contact count, so a growing supporter list keeps raising the price. It is the shallowest discount in this comparison.
Why is Klaviyo ranked last for nonprofits?
It is profile-billed and built for ecommerce, with no nonprofit discount. A donor list produces none of the order data Klaviyo is designed around, so you pay full price for unused capability.
