Mailchimp is the better choice if you need advanced automation, segmentation, and a large integration ecosystem. Constant Contact is better if you want straightforward campaign sending, event management, and phone support without a learning curve. Both charge by contact count, and both get expensive fast as your list grows.
The short version
These two platforms have been compared for fifteen years, and the honest summary has not changed much: Mailchimp is a marketing platform that grew capable and complicated; Constant Contact is a newsletter tool that stayed approachable and limited. Which is "better" depends entirely on whether you value ceiling or floor.
| Dimension | Mailchimp | Constant Contact |
|---|---|---|
| Best for | Ecommerce, growing teams, automation-heavy use | Small business, nonprofits, event-driven orgs |
| Learning curve | Moderate to steep | Gentle |
| Automation depth | Strong — branching, conditional logic | Basic — mostly linear sequences |
| Segmentation | Advanced behavioral and predictive | Straightforward list and tag based |
| Templates | Large library, flexible editor | Solid library, simpler editor |
| Event management | Not a core feature | Built in — a genuine differentiator |
| Integrations | Very large ecosystem | Smaller but covers the essentials |
| Support | Email and chat; phone on higher tiers | Phone support widely available |
| Free plan | Limited free tier | Trial only |
| Pricing model | Per contact, tiered by feature | Per contact, tiered by feature |
Where Mailchimp genuinely wins
Automation with branching logic. If your flows need to ask questions — did they open, did they purchase, are they in this segment — Mailchimp handles that natively. Constant Contact's automation is mostly linear: send this, wait, send that. For an abandoned cart sequence that behaves differently by cart value, this difference is decisive.
Segmentation. Mailchimp lets you build audiences from combinations of behavior, purchase history, engagement recency, and custom fields. Since relevance is the largest single lever on email performance, this capability translates directly into revenue for anyone with more than a few thousand contacts.
Ecommerce depth. Product recommendations, purchase-triggered flows, and revenue attribution are more mature. If you run a store, this is usually the deciding factor.
Integration breadth. Whatever obscure tool your team uses, there is a reasonable chance a Mailchimp connector already exists. Constant Contact covers the mainstream well but thins out at the edges.
Reporting. Comparative reporting, revenue attribution, and audience insights go meaningfully deeper.
Where Constant Contact genuinely wins
Speed to first send. A non-technical user can create an account, import a list, pick a template, and send a decent-looking campaign in under thirty minutes. That is not nothing. Plenty of small businesses have a Mailchimp account they never used because they got lost on the way.
Phone support. Constant Contact answers the phone, and for owner-operators who do not want to file a ticket and wait, this matters more than any feature comparison. Mailchimp's phone access is gated to higher tiers.
Event management. Registrations, ticketing, and attendee tracking are built in. For nonprofits, associations, and anyone running regular events, this eliminates a separate tool and a separate bill.
Predictability. Fewer features means fewer ways to misconfigure something. Teams without a dedicated marketer often ship more consistently on the simpler platform.
Cost: the part both make hard to compare
Both price by contact count, and both make you pay for the same subscriber across multiple audiences or lists in certain configurations. Neither publishes a simple per-thousand rate you can compare on a napkin, because tier boundaries and feature gates interact.
The pattern to watch for is the growth penalty. Costs on both platforms escalate steeply as you cross contact thresholds — and the escalation is unrelated to whether those extra contacts are actually engaged. You end up paying for the 40% of your list that has not opened anything in a year, which creates a perverse incentive against the list hygiene that would improve your deliverability.
Three questions to ask before you commit to either:
- What does this cost at 3x my current list size? Model it now, not after the migration.
- Which features are gated above my tier? Automation and reporting are commonly locked behind upgrades on both.
- Am I paying for unengaged contacts? If so, budget time for quarterly pruning — or choose a platform that does not charge by contact at all.
How to choose between them
- Choose Mailchimp if you run an online store, need conditional automation, want deep segmentation, or expect a marketing hire in the next year who will use the ceiling.
- Choose Constant Contact if you run events, want phone support, have no dedicated marketer, or simply need a reliable monthly newsletter to go out without fuss.
- Choose neither if your primary pain is per-contact pricing, deliverability, or the fact that half your budget is going to storage of addresses rather than to sending.
That third option is worth taking seriously. A lot of teams comparing these two are really asking "which of these two do I dislike less?" — which is a sign the category has changed and the shortlist has not. It is worth widening the comparison before you sign an annual contract; our side-by-side email platform comparison puts pricing models and feature gates next to each other honestly.
The third option: pricing that does not punish growth
The structural complaint about both platforms is the same. You are charged for contacts rather than for value delivered, so the cost of growing your list rises faster than the revenue from it. IGSendMail takes the opposite approach: unlimited contacts on paid plans starting at $19/month, a free plan up to 2,500 contacts, and high inbox deliverability with SPF, DKIM, and DMARC configured automatically rather than left as a support article you were supposed to read.
Practically, that changes behavior. When adding subscribers does not raise your bill, you stop treating list growth as a cost center and start segmenting aggressively, because there is no penalty for keeping a re-engagement audience around. You also get AI subject-line and copy tools, built-in A/B testing, 65+ responsive templates, and free 24-hour migration if you are moving an existing list — which removes most of the reason people stay on a platform they have outgrown.
If you are specifically weighing a switch, read the detailed Mailchimp alternative breakdown or the Constant Contact alternative comparison, both of which cover migration mechanics and what actually transfers.
A practical evaluation process
- List your five must-have workflows — not features, workflows. "Recover abandoned carts with a three-email sequence" is a workflow. "Automation" is not.
- Trial each platform and build one real campaign, end to end, including the segment and the automation. Demos hide friction; building reveals it.
- Price it at your projected 12-month list size.
- Test support before you buy. Send a hard question during the trial and time the answer.
- Check migration in both directions. How easily can you export contacts, templates, and automation logic if you leave? A platform that makes leaving painful is telling you something.
Frequently asked questions
Is Mailchimp or Constant Contact easier to use?
Constant Contact is easier for a first-time sender — most people can import a list and send a campaign within half an hour. Mailchimp has a steeper learning curve but a much higher ceiling once you need branching automation and behavioral segmentation.
Which is cheaper, Mailchimp or Constant Contact?
Neither is reliably cheaper, because both price by contact count and gate features by tier. Compare them at your projected 12-month list size rather than today's, since costs on both escalate steeply as your list grows.
Does Constant Contact have automation?
Yes, but it is largely linear — timed sequences triggered by a signup or a click. It lacks the conditional branching that lets a flow behave differently based on purchase history, engagement, or segment membership.
Which is better for ecommerce?
Mailchimp, by a clear margin. Product recommendations, purchase-triggered automation, and revenue attribution are considerably more developed than Constant Contact's ecommerce features.
Can I switch platforms without losing my list?
Yes. Contacts, tags, and custom fields export cleanly from both. Templates and automation logic usually need rebuilding, which is why a provider offering free migration assistance removes most of the switching cost.
