Constant Contact vs Mailchimp: The Pricing Model Decides It
Feature lists on email platforms change every quarter and both of these do the same core job. Two things genuinely decide the choice: how each one charges, and what happens to your list if you want to leave.
The two charging bases
Email platforms price either on the number of contacts you store or on the number of emails you send, and the difference determines which is cheaper for a given business rather than which is cheaper in general.
A large list emailed rarely is cheap on a send-based plan and expensive on a contact-based one. A small list emailed frequently is the reverse. Work out which shape you are before comparing headline prices, because the headline is quoted at a tier that may not be yours.
Check also how each counts an unsubscribed or bounced contact. Some plans keep charging for records you can no longer email, which quietly raises the effective price as a list ages.
Why an unexpected charge appears on a statement
A recurring question about these products is not about features at all. It is somebody finding a charge they do not recognise. Email subscriptions are commonly sold bundled with website hosting or a domain purchase, sometimes on a trial that converts automatically.
If a charge appears that you did not knowingly set up, check the hosting or domain account first rather than the email platform, because that is where the bundle was bought and where the cancellation control usually lives.
If it is genuinely unrecognised, cancel the subscription at source and then, if a refund is refused, raise it with the card provider: a subscription converted from a trial without clear consent is a chargeback case rather than a lost cause.
The thing that matters more than either product
Whether you can take the list with you. Both platforms let you export subscribers, and that export is the asset: an email list is one of the few marketing assets a business actually owns rather than rents.
Test the export before you need it. A platform is a supplier and suppliers change their pricing, get acquired, or discontinue a plan you depend on, and the moment to discover an export limitation is not the moment you are leaving.
What does not export cleanly is automation logic and campaign history, so expect to rebuild sequences rather than migrate them. That is the switching cost, and it is worth knowing before building something elaborate.
Deliverability, which is mostly your job
Both platforms have good sending reputations, so the differences in whether your email arrives come mostly from your own setup and behaviour rather than from the brand.
The controllable parts: authenticating your sending domain, sending only to people who asked, removing hard bounces promptly, and not mailing a list that has gone cold for a year. A dormant list emailed suddenly is the classic route into a spam folder.
Neither platform will rescue a list built by buying addresses. That is a rule under UK data protection as well as a deliverability problem, and it is the fastest way to have an account suspended.
The UK compliance points
Consent must be specific and recorded, and you need to be able to show when and how somebody subscribed. That is a data-protection requirement rather than a platform feature, and the platform storing it for you does not make it optional.
Every marketing email needs a working unsubscribe and an identifiable sender. Both platforms handle this automatically, which is a reasonable argument for using one rather than sending from your own mailbox.
And a privacy notice explaining what you do with the addresses. See the obligations that come with publishing.
When neither of them is the right tool
Two situations where a mainstream email platform is the wrong purchase. If the list is under a few hundred people and you send occasionally, the free tiers cover it and paying for either is premature: the upgrade prompt is a marketing surface rather than a limit you have reached.
And if what you actually want is transactional email — order confirmations, password resets, receipts, that is a different product with different pricing, and sending it through a marketing platform is both more expensive and worse at arriving.
There is a third case worth naming: if the plan is to email a list you have not built yet, the platform is the last decision rather than the first. Building the list is the work, and choosing software before there is anybody to send to is the most common way this project stalls.
Choosing without reading another comparison
Count your contacts and estimate your monthly sends. Price both platforms at your actual numbers rather than at the advertised tier. Check the export function works. Then pick whichever is cheaper at your shape and stop thinking about it.
The feature differences between mainstream email platforms are not what determines whether email works for a business. What you send and to whom is, and no platform choice compensates for getting that wrong.

Frequently asked questions
Which is cheaper?
Depends on your shape rather than in general. Platforms charge either per contact stored or per email sent, a large list mailed rarely is cheap on one basis and expensive on the other. Price both at your actual numbers.
Why is there a charge I do not recognise?
Email subscriptions are commonly bundled with website hosting or a domain purchase, sometimes as a trial that converts automatically. Check the hosting or domain account first, because that is usually where the cancellation control lives.
Can I get a refund on a subscription I did not mean to start?
Cancel at source first. If a refund is refused, a trial that converted without clear consent is a legitimate chargeback case with your card provider rather than a lost cause.
Can I move my list to another platform?
Yes: subscriber exports work on both, and the list is the asset you own. Automation logic and campaign history generally do not transfer, so expect to rebuild sequences rather than migrate them.
Which has better deliverability?
Both have good sending reputations, so the differences come mostly from your setup: authenticating your domain, mailing only people who asked, removing bounces, and not waking a list that has been dormant for a year.
What do I need to comply with in the UK?
Specific, recorded consent you can evidence, a working unsubscribe and identifiable sender on every message, and a privacy notice. Buying address lists breaches the rules and gets accounts suspended.
