USE-CASE GUIDE — NONPROFITS
Best Email Platforms for Nonprofits in 2026
Donor segmentation, appeal sequences, volunteer comms, and which vendors actually discount for registered charities.
Nonprofit email has constraints a business does not. Your list mixes donors, volunteers, beneficiaries, board members, and event attendees, and the same message rarely suits two of those groups. Budget approval runs through a board rather than a growth target. And the people sending the email are often part-time or volunteers, which means the tool has to be learnable by someone who will not attend training. That pushes the decision away from feature depth and toward three things: does a genuine free or discounted tier exist, can a non-specialist segment the list without breaking it, and is there human support when an appeal has to go out on Thursday. Nonprofit discounts are real but inconsistently published — some vendors advertise a percentage, others handle it case-by-case through sales. We have flagged which is which rather than quoting a number we cannot verify. We judged the four platforms below on free-tier usefulness, verified discount availability, donor and volunteer segmentation, ease of use for occasional senders, and support quality.

What we love · what we don't
What we love
- Free tiers make it possible to start a supporter programme with no budget approval
- Event and donation integrations have improved across the category
- Two of the four vendors here operate nonprofit discount programmes
What we don't
- Nonprofit discount terms are poorly published and change without notice
- Contact-based pricing punishes organisations for keeping lapsed donor records
- Donor stewardship features still lag behind ecommerce equivalents
The ranking
1. Mailchimp
Mailchimp remains the default for small charities for practical reasons. Almost every volunteer has used it somewhere, the templates are hard to make ugly, and the free tier is enough to run a monthly update to a first list of supporters without a purchase order. Basic donor tagging and simple automations cover a welcome message and an annual appeal.
The problem arrives with growth. Pricing rises steeply with contact count, and the tiers gate the segmentation and automation you eventually need for donor stewardship. Nonprofit discounting is not consistently published, so treat it as something to ask about rather than assume. Many organisations outgrow Mailchimp within two years and pay a migration cost they could have avoided.
Pros
- Genuinely free to start on a small list
- Interface most volunteers already know
- Templates that survive non-designers
- Wide integration catalogue including donation tools
Cons
- Cost escalates sharply with contact count
- Automation and segmentation gated behind higher tiers
- Nonprofit discounting not clearly published
Who it's for
Organisations under a few hundred contacts, sending monthly updates and an annual appeal.
Skip it if
You already have thousands of supporters and need real donor segmentation.
2. Constant Contact
Constant Contact has served nonprofits longer than almost anyone in this category, and it shows in the details: event registration and ticketing tools, donation-friendly landing pages, and support you can telephone rather than queue for in a chat widget. For a small team where the email sender is not a marketer, that support line has genuine value.
It also runs a nonprofit discount programme — historically prepay-based — but published terms change, so confirm current eligibility and the percentage directly with their team before budgeting. The editor and automation feel dated next to MailerLite, and there is no free tier, only a trial.
Pros
- Nonprofit discount programme available (confirm current terms)
- Phone support included
- Event registration and ticketing built in
- Low annual entry price
Cons
- No free plan
- Automation is basic
- Interface feels older than rivals
Who it's for
Established nonprofits running events and appeals with a small, non-specialist team.
Skip it if
You need modern automation or a free tier.
3. MailerLite
MailerLite gives a small nonprofit more per dollar than anything else here. Landing pages and a simple website builder are included, so a campaign page does not require a web developer. Segmentation by interest group — donors, volunteers, newsletter-only — is straightforward, and the editor is clean enough that a volunteer can produce something respectable.
It has historically offered a nonprofit discount; confirm the current figure with their team rather than relying on an old blog post. Support is email-based, and there is no event-registration tooling, so ticketed galas need a separate vendor.
Pros
- Lowest paid entry price of the group
- Landing pages and websites included
- Clean, learnable editor
Cons
- No phone support
- No event registration tooling
- Free tier limited to 250 subscribers
Who it's for
Lean organisations that need design and pages without a bigger subscription.
Skip it if
Events and ticketing are central to your fundraising.
4. Klaviyo
If your organisation sells merchandise, tickets, or memberships through Shopify or a similar system, Klaviyo's data model becomes relevant: it can segment on transaction history, average gift size, and recency in ways the other three cannot without exports. Lapsed-donor and second-gift flows are structurally the same problem as ecommerce win-back.
For a purely donation-driven charity with no commerce, it is overkill and overpriced. There is no widely published nonprofit discount programme, so budget at commercial rates unless their team tells you otherwise.
Pros
- Best segmentation on transaction and gift history
- Strong flow reporting for appeal performance
- SMS in the same flows as email
Cons
- Expensive relative to nonprofit budgets
- No clearly published nonprofit discount
- Steeper learning curve
Who it's for
Nonprofits running a real commerce or ticketing operation alongside fundraising.
Skip it if
You take donations only and have no transactional data.
How we chose these platforms
We weighted free-tier usefulness, verified nonprofit discount availability, donor and volunteer segmentation, learnability for occasional senders, and support channels.
Discount percentages change and are often negotiated case-by-case, so we point you to confirm current terms with each vendor rather than publishing a figure that may be out of date. Scores shown are BestSends platform scores from our standing test cycles.

Workflow example: a year-end appeal that respects your donors
A local charity with 6,800 contacts: 900 past donors, 400 volunteers, and the rest newsletter subscribers. Last year the same appeal went to everyone four times and unsubscribes spiked.
- 01
Segment before you write
Split into recurring donors, one-off donors from the last 24 months, lapsed donors, volunteers, and never-donated subscribers. Five messages, not one.
- 02
Ask recurring donors to upgrade, not to give again
They already give. The ask is a modest increase or a matching challenge — not a cold appeal.
- 03
Give lapsed donors an impact update first
One email showing what their previous gift funded, then the ask. Skipping this is why reactivation appeals fail.
- 04
Ask volunteers for reach, not money
A share-and-forward request converts far better than a donation request to people already giving time.
- 05
Cap the sequence at three emails and honour preferences
Add a visible "opt out of appeals but keep the newsletter" link. It saves more addresses than any subject line.
- 06
Suppress on gift, immediately
The moment someone donates, they exit the sequence and enter a thank-you flow with a receipt and one impact story.
Segmenting the ask by relationship, and giving supporters a way to opt out of appeals without leaving the list, is what stops a year-end campaign from costing you next year’s audience.

Frequently asked questions
Mailchimp, for a first list — the free tier covers up to 500 contacts with send caps, and most volunteers can use it without training. Once you pass that ceiling, MailerLite is usually cheaper than upgrading Mailchimp, so plan the move rather than defaulting into a higher tier.
