Mailchimp vs Constant Contact for Nonprofits (2026)
Mailchimp vs Constant Contact for nonprofits compared on pricing, ease of use, and nonprofit discounts. See which tool fits — plus a simpler alternative.
Last updated: March 27, 2026
TL;DR: Neither Mailchimp nor Constant Contact is the best fit for most nonprofits in 2026. Mailchimp charges for unsubscribed contacts and has gutted its free plan to just 250 contacts. Constant Contact eliminated its free plan entirely and requires prepayment for its nonprofit discount. For organizations that need to send member updates without marketing complexity, Groupmail offers unlimited contacts from $15/month with no application needed and human support on every plan — including Free.

Email remains the most effective outreach channel for nonprofits, with Nonprofit Tech for Good reporting that 86% of nonprofits use email marketing and 33% of donors saying email most inspires them to give. But the two platforms nonprofits hear about most — Mailchimp and Constant Contact — have both moved in directions that make them harder to recommend.
Disclosure: We're the team behind Groupmail — simple email software for organizations since 1996. We'll be upfront about where we fit and honest about alternatives.
Why Do Nonprofits Need Simple Email Tools?
Most nonprofits don't run marketing operations — they send member updates, event reminders, and fundraising appeals, and they need a tool any volunteer can use.
According to the 2025 Nonprofit Tech for Good Survey, 45% of nonprofits send newsletters monthly and just 13% send weekly. The typical nonprofit email program is run by a staff member or volunteer who wears several hats, not a dedicated email marketer. Nonprofits experience an average email open rate of 28.59%, according to Neon One — higher than the for-profit average of 21%. That suggests members genuinely want these updates. The challenge isn't engagement; it's finding a tool that doesn't require training to use.
The M+R Benchmarks report found that nonprofits raise an average of $58 for every 1,000 fundraising emails sent — making email by far the most cost-effective digital fundraising channel. The tool you choose should help you send reliably, not slow you down with features built for e-commerce marketers.
💡 Tip: Before comparing platforms, write down your actual needs: how many contacts you have, how often you send, and whether a volunteer or staff member manages your emails. Most nonprofits need far less than Mailchimp or Constant Contact offer.
What Should Nonprofits Look for in Email Software?
Nonprofits should prioritize simplicity, transparent pricing with unlimited contacts, human support, and the ability to hand the tool off when volunteers change.
The average nonprofit email list sits at around 4,000 contacts, according to Nonprofit Tech for Good's email statistics. At that size, contact-based pricing matters — platforms that charge per contact can cost $50–$135/month for what amounts to a monthly newsletter. Look for a free plan that's genuinely usable (not just 250 contacts), transparent pricing that doesn't penalize list growth, and support from real people rather than chatbots. For volunteer-run organizations, ask one question above all: can a new volunteer pick this up in 10 minutes without training?
What Are the 3 Best Email Tools for Nonprofits?
Groupmail leads for simplicity and value, Mailchimp for advanced automation, and Constant Contact for event-heavy organizations — but both incumbents come with significant trade-offs.
| Tool | Best For | Free Plan | Starting Price | Contacts Included | Human Support |
|---|---|---|---|---|---|
| Groupmail | Simplicity + human support | 500 contacts | $15/mo | Unlimited (paid) | Yes — real people |
| Mailchimp | Advanced automation | 250 contacts | $13/mo | 500 (scales with plan) | Paid plans only |
| Constant Contact | Event management | None | $12/mo | 500 (scales with plan) | Phone + chat |
1. Groupmail
Best for: Organizations that want to send member updates without becoming email marketing experts Pricing: Free (500 contacts) | Community $15/mo | Continuity $29/mo | Business $49/mo | All paid plans: unlimited contacts Website: groupmail.io
Groupmail is purpose-built for the organizations that Mailchimp and Constant Contact have outgrown. Where both incumbents have added layers of marketing automation, CRM features, and e-commerce integrations, Groupmail stays focused on what most nonprofits actually do: send a newsletter or update to their members. Set up takes about 10 minutes, and Groupmail manages email delivery on all plans — no DNS records, no third-party sending service, no technical setup.
Every paid plan includes unlimited contacts, which removes the anxiety of watching your list grow toward a pricing threshold. The Community plan at $15/month sits well under typical board-approval thresholds, and there are no discount applications or documentation requirements — Community-First pricing means $15/month is the default price for community organizations. Credit top-ups at $5/1,000 emails are available on all plans, including Free, for months when you send more. Human support from real people is included on every plan, including Free.
For organizations with volunteer turnover, the Continuity plan ($29/month) includes an annual handover call — when one volunteer leaves and another takes over, Groupmail's team walks the new person through the account. No other email platform offers this.

What's missing: Groupmail doesn't offer complex automation workflows, advanced segmentation, or a large integration library. If your nonprofit runs multi-step donor nurture sequences or needs deep CRM integration, you'll want a more feature-rich tool. For most nonprofits sending member updates, these trade-offs won't matter.
Key Takeaway: Groupmail does one thing well — letting organizations send updates to their members without complexity. The unlimited contacts, human support, and volunteer handover call make it the best fit for nonprofits that don't need marketing automation.
2. Mailchimp
Best for: Nonprofits with dedicated marketing staff who need advanced segmentation and automation Pricing: Free (250 contacts, 500 emails/mo) | Essentials from $13/mo | Standard from $20/mo | Premium from $350/moWebsite: Mailchimp
Mailchimp is the most recognized name in email, and for good reason — it offers deep automation, predictive analytics, and hundreds of integrations. For nonprofits with a dedicated communications team running multi-step donor journeys, it remains a capable tool. According to EmailToolTester, Mailchimp's email editor is among the most modern available, and its reporting goes well beyond basic open and click rates.
However, Mailchimp's pricing has become significantly harder to justify for nonprofits. As of January 2026, the free plan was cut to just 250 contacts and 500 emails per month — down from 2,000 contacts pre-2022. At 5,000 contacts, Essentials costs $75/month and Standard runs $100/month. The 15% nonprofit discount is the lowest among major competitors and requires a 501(c)(3) determination letter submitted before purchasing a paid plan — no retroactive application.
The most significant issue for nonprofits: Mailchimp counts subscribed, unsubscribed, and non-subscribed contacts toward your plan limit. M+R Benchmarks 2025 found nonprofits average a 9.7% unsubscribe rate. A 5,000-contact list accumulates roughly 485 unsubscribed contacts per year you're still paying for, unless you manually archive them. Trustpilot rates Mailchimp 2.8 out of 5 from over 1,300 reviews.

What's missing: Simplicity. Mailchimp's interface has grown complex enough that volunteers and non-technical staff often need training to use it effectively. The free plan is no longer viable for most organizations, and the pricing model penalizes list growth. If your nonprofit doesn't use advanced automation, you're paying for features that sit idle.
3. Constant Contact
Best for: Event-heavy nonprofits with a budget for annual prepayment Pricing: Lite $12/mo | Standard $35/mo | Premium $80/mo (all at 500 contacts, scales with list size) Website: Constant Contact
Constant Contact has served nonprofits for over 30 years, and its standout feature remains event management — handling registrations, invitations, RSVP tracking, and follow-up emails from within the platform. If your nonprofit runs frequent galas, volunteer days, or fundraising events, this integration is genuinely useful and something Mailchimp doesn't offer natively.
The nonprofit discount is 20% off with a 6-month prepayment or 30% off with a 12-month prepayment, but only on Standard plans and above. At 2,500 contacts on the Standard plan ($50/month before discount), a nonprofit prepaying annually pays roughly $35/month after the 30% discount. That's still more than double Groupmail's Community plan. Constant Contact also offers a 50% discount through TechSoup for eligible nonprofits, though this requires TechSoup membership and verification.
The biggest problem for nonprofits: Constant Contact eliminated its free plan entirely in 2025. And cancellation still requires a phone call — you must dial 855-229-5506 during business hours (Mon–Fri 8am–8pm ET). Users consistently report hold times and retention pitches. Sitejabber rates Constant Contact 1.3 out of 5 from 82 reviews. The BBB logged complaints about cancellation difficulties and billing disputes, including from nonprofit religious organizations.
For more context, see our Constant Contact Alternatives for Nonprofits and Constant Contact Pricing for Nonprofitsguides.
What's missing: A free plan, simple cancellation, and affordable pricing without prepayment. Automation capabilities lag behind Mailchimp, and the Lite plan offers only basic features at $12/month. For nonprofits that don't run events, the main differentiator disappears — and what remains is an expensive platform with limited flexibility.

How Do Nonprofit Discounts Actually Compare?
Mailchimp's 15% is the lowest major discount available; Constant Contact requires prepayment for its 20–30%; Groupmail doesn't need a discount because $15/month is already the community organization price.
| Tool | NP Discount | How to Claim | Requires Prepay? | Charges Unsubscribes? | Unlimited Contacts? |
|---|---|---|---|---|---|
| Groupmail | $15 IS the price | No application | No | No | Yes (paid plans) |
| Mailchimp | 15% | 501(c)(3) letter before purchase | No | Yes | No |
| Constant Contact | 20–30% | Contact sales, prepay 6–12 months | Yes (6 or 12 months) | No | No |
The discount landscape tells a story about priorities. Mailchimp's 15% discount — the lowest among major competitors — must be requested before purchasing and cannot be applied retroactively, according to Mailchimp's own nonprofit discount page. Constant Contact's more generous 30% discount requires locking in 12 months of prepayment, which isn't always feasible for organizations with tight cash flow. Groupmail skips the discount model entirely — Community-First pricing means $15/month is the standard rate for organizations, no application required.
For a nonprofit with 2,500 contacts sending one monthly newsletter, the annual cost comparison is stark: Mailchimp Standard after 15% discount runs roughly $612/year; Constant Contact Standard after 30% annual prepay is around $420/year; Groupmail Community is $150/year (or $180 monthly). Groupmail's price doesn't change based on contact count because every paid plan includes unlimited contacts.
Which Tool Is Right for Your Nonprofit?
Groupmail fits most nonprofits — especially those run by volunteers or small teams. Choose Mailchimp only if you run complex donor automation, and Constant Contact only if event management is essential.
If your nonprofit sends a monthly or weekly newsletter to members, donors, or volunteers, and the person managing email isn't a marketing professional, Groupmail is the straightforward choice. The unlimited contacts, $15/month pricing, and human support eliminate the most common frustrations nonprofits face with both Mailchimp and Constant Contact.
Choose Mailchimp if your organization has a dedicated communications or development team that will actively use predictive segmentation, multi-step automation, and A/B testing across channels. Be prepared for costs to scale significantly — and archive unsubscribed contacts regularly.
Choose Constant Contact if event management is central to your nonprofit's operations and you can commit to annual prepayment. The event tools are genuinely useful for organizations that run frequent galas, volunteer events, or ticketed programs.

FAQ
Is Mailchimp or Constant Contact better for small nonprofits? Neither is ideal for most small nonprofits in 2026. Mailchimp's free plan now covers only 250 contacts, and Constant Contact has no free plan at all. Both platforms have grown in complexity beyond what most small nonprofits need. Groupmail's free plan supports 500 contacts with 1,000 monthly emails and includes human support — making it a better starting point for organizations just getting set up.
Does Mailchimp charge for unsubscribed contacts? Yes. According to Mailchimp's pricing documentation, subscribed, unsubscribed, and non-subscribed contacts all count toward your plan limit. You must manually archive contacts to stop being billed for them. With an industry-average unsubscribe rate of 9.7% for nonprofits according to M+R Benchmarks, this adds up quickly over time.
Can I cancel Constant Contact online? No. Constant Contact requires you to call 855-229-5506 during business hours (Mon–Fri 8am–8pm ET) to cancel your account. Multiple review sites report hold times and retention pitches during the cancellation call. Groupmail offers one-click cancellation in Current Plan → Manage Plan with no phone calls or hold times.
Why is Groupmail so affordable for nonprofits? Groupmail uses Community-First pricing — $15/month is the standard price for community organizations, not a discounted version of a higher price. There are no application forms, no documentation requirements, and no discount codes. This keeps the price simple and eliminates the administrative burden that nonprofit discounts create at other platforms. Groupmail has operated since 1996 and serves over 100,000 organizations across 160 countries.
What's the real cost of Mailchimp for a nonprofit with 5,000 contacts? At 5,000 contacts, Mailchimp Essentials costs $75/month and Standard costs $100/month before any discount. After the 15% nonprofit discount, expect to pay roughly $64–$85/month. By comparison, Groupmail's Community plan at $15/month includes unlimited contacts — the same price whether you have 500 or 50,000 members.
Does Constant Contact offer a free plan for nonprofits? No. Constant Contact eliminated its free plan in 2025. The only free option is a 14-day trial. After the trial, the least expensive plan (Lite) starts at $12/month for 500 contacts, with limited features including no automation and only basic reporting. Groupmail's free plan is permanently free with 500 contacts and 1,000 emails per month.
Which platform has better email deliverability? Deliverability depends on many factors including list quality, content, and sending frequency — not just the platform. Constant Contact reports a 97% deliverability rate, and Mailchimp regularly benchmarks well in third-party deliverability tests by EmailToolTester. Groupmail manages email delivery on all plans, handling the technical infrastructure so organizations don't need to configure DNS records or worry about sending reputation.
What happens when the volunteer managing our email changes? This is a common challenge for nonprofits, churches, and PTAs. Most platforms offer no support for transitions. Groupmail's Continuity plan ($29/month) includes an annual handover call — when a volunteer leaves, Groupmail's team walks the new person through the account. No other major email platform offers this kind of transition support.
Conclusion
Mailchimp and Constant Contact both built their reputations serving nonprofits, but in 2026 both have evolved into marketing platforms that are more complex and expensive than what most organizations need. For nonprofits that simply want to keep their members informed, Groupmail offers the straightest path — unlimited contacts, human support, and a price that doesn't require board approval.
