Mailchimp vs Constant Contact for Associations (2026)

Mailchimp vs Constant Contact for Associations: Full Overview

Mailchimp and Constant Contact are the two most compared email platforms in the membership and association space. Both were built for small businesses and later added nonprofit features — but neither was designed for associations sending dues renewals, chapter updates, and AGM invitations to a roster of members.

Mailchimp launched in 2001 and grew into a full marketing platform with landing pages, social ads, CRM features, and automation workflows. Intuit acquired Mailchimp in 2021 for $12 billion. Its free plan (500 contacts, 1,000 emails per month) is the strongest draw for small associations with no communications budget.

Constant Contact has been in the email space since 1995. It focuses on simplicity and added event management tools that are genuinely useful for associations running an annual conference, AGM, or chapter meetings. Its up-to-30% prepay discount is the most generous among major platforms — but it removed its free plan in 2023, and crucially, the discount runs through TechSoup, which excludes the 501(c)(6) trade and professional associations that make up most of the sector.

Core Email Features Compared

Both platforms include the essential email features associations need: drag-and-drop editors for the member newsletter, contact management for the membership roster, signup forms for new-member recruitment, basic analytics, and scheduled sending for dues-renewal cycles.

Mailchimp gates its most useful features behind higher plans. Email automation — useful for renewal reminder sequences and new-member welcome series — requires Standard ($20/month at 500 contacts) or higher. A/B testing and send-time optimisation are also Standard-tier. The free plan includes only basic email sends and limited templates.

Constant Contact takes a similar approach with fewer tiers. Its Standard plan includes basic automation, segmentation (handy for chapters and membership categories), and social posting. Event management is available on all paid plans — a genuine differentiator for associations with active event calendars. A/B subject-line testing requires Premium.

For associations sending member updates and occasional event invitations, both platforms provide more features than most membership bodies will use. The question is rarely about feature gaps — it is about what your association will actually pay for the features it needs, especially without access to a discount.

Where Mailchimp Adds Value for Associations

Mailchimp's strongest case for associations starts with its free plan. For small membership bodies with fewer than 500 active members and no budget, Mailchimp is the only major platform offering a free entry point since Constant Contact removed its free tier in 2023.

Beyond the free plan, Mailchimp's integration ecosystem is its second advantage. With over 300 native integrations — including Salesforce, Stripe, Eventbrite, WordPress, and many association management systems — associations running multiple tools can connect them without third-party middleware.

Mailchimp's reporting is also more detailed than Constant Contact's. Campaign analytics include click maps, audience growth charts, and member segmentation by chapter or membership category. For associations that report engagement metrics to a board or membership committee, Mailchimp provides more granular data out of the box.

The tradeoff is complexity. Mailchimp's dashboard has grown cluttered as Intuit has added marketing features most associations will never use — and the staff or volunteer time spent learning the platform is a real cost, especially when officers rotate annually.

Where Constant Contact Adds Value for Associations

Constant Contact's clearest advantage for associations is its built-in event management. Associations that run an annual conference, AGM, CPD sessions, regional chapter meetings, or networking events can create event pages, manage registrations with member pricing, collect payments, and send follow-up emails — all without leaving the platform.

The up-to-30% nonprofit prepay discount is the most generous among major email platforms. While the base prices are higher than Mailchimp's, the 12-month prepay discount brings Constant Contact's effective cost below Mailchimp's at most contact tiers above 2,500 — but only for associations that hold 501(c)(3) charitable status and can pass TechSoup verification. Most 501(c)(6) associations cannot, and pay full price.

Constant Contact also offers phone support on paid plans — unusual in the email platform space. For associations with non-technical membership coordinators or volunteer officers who need guidance, being able to call a real person is a meaningful differentiator that Mailchimp does not match.

The tradeoff: no free plan, higher base prices, the prepay requirement to unlock the best discount, the 501(c)(3)-only eligibility, and limited automation compared to Mailchimp's Standard tier and above.

Free Plan Comparison

The free plan question is straightforward: Mailchimp has one, Constant Contact does not.

Mailchimp's free plan includes 500 contacts and 1,000 email sends per month. It includes the drag-and-drop editor, basic templates, and signup forms — enough for a small association sending member updates to a single chapter. It does not include automation, A/B testing, or scheduled sending beyond limited options. There is also a daily sending limit of 500 emails, which can constrain a large all-member announcement.

Constant Contact offered a 60-day free trial historically and removed even that in some markets. For associations with zero budget, Constant Contact is not an option at all.

Groupmail also offers a free plan at the same 500-contact, 1,000-email limits. The key difference: when your association outgrows the free tier, Groupmail's paid plan is $15/month for unlimited members — compared to Mailchimp's tiered pricing that scales with your roster, with no discount available to most associations to soften the climb.

Migration Considerations for Associations

Switching email platforms is straightforward but requires planning. Both Mailchimp and Constant Contact allow CSV export of contacts including email addresses, names, chapter tags, and custom fields. Neither exports email campaign history or automation workflows.

If moving from Mailchimp to Constant Contact (or vice versa), expect to rebuild your newsletter templates, recreate any renewal automations, and re-import your member roster. Plan for 2-4 hours of setup time for a typical association account, ideally outside your renewal season or the run-up to your annual conference.

If considering Groupmail as an alternative, the migration is simpler: export your members from Mailchimp or Constant Contact as a CSV, import into Groupmail, and start sending. There are no automations to recreate because Groupmail focuses on member communication rather than marketing workflows. Groupmail also offers migration assistance on the Continuity plan ($29/month) — useful when the move falls to a membership coordinator alongside their day job.

One critical note: both Mailchimp and Constant Contact charge for unsubscribed members. When you export, export only active members to avoid paying for lapsed contacts on any new platform.

Deliverability Track Records

Email deliverability — the percentage of emails that reach the inbox rather than spam — matters more than features for association communication. A well-designed dues reminder is worthless if it lands in spam during your renewal window.

Both Mailchimp and Constant Contact maintain strong deliverability reputations. Industry tests consistently place both platforms in the 85-95% inbox placement range, though results vary by list quality, content, and sender reputation. Associations that send only to engaged, current members typically see deliverability at the higher end.

Mailchimp enforces stricter list hygiene and will suspend accounts with high bounce rates — a risk for associations with old, unmaintained rosters full of lapsed members. Constant Contact is somewhat more lenient but still monitors sender reputation actively.

Groupmail handles deliverability through managed email delivery — the platform manages the technical infrastructure (SPF, DKIM, DMARC) and sending reputation on behalf of each association. This means association staff and volunteers do not need to configure DNS records or monitor deliverability metrics themselves. For associations without a technical volunteer, managed delivery removes a category of problems entirely.

For Associations Specifically

Neither Mailchimp nor Constant Contact was built for associations. Both started as small-business tools and added nonprofit discounts as a customer acquisition strategy — discounts that, for associations, often turn out to be unavailable. The dashboards reflect their origins: e-commerce metrics, conversion tracking, and marketing automation most membership bodies never use.

The first problem is eligibility. Both discounts run through TechSoup, which verifies 501(c)(3) charitable status. The typical trade association, professional body, business league, or chamber of commerce is a 501(c)(6) — explicitly excluded. So the headline 15% and 30% discounts that make these platforms look affordable for charities simply do not apply, and most associations pay full list price.

The second problem is cost structure. Both platforms charge based on total contacts, including lapsed members who unsubscribed years ago. An association with 20 years of history may have 2,000 current dues-payers and 5,000 lapsed members on the same roster. Both platforms bill at the 7,000-contact tier — full price, with no discount to offset it.

The third is volunteer turnover. Membership directors, secretaries, and board officers rotate on annual AGM cycles, and neither platform offers transition support. Groupmail was built for exactly this: organisations with members (not customers), volunteer-led leadership, and dues-funded budgets. Flat $15/month pricing regardless of tax status, no charge for unsubscribes, and annual handover calls when your board changes.
