Mailchimp vs Klaviyo

The rule that decides it

Service businesses, professional services and business-to-business senders: Mailchimp, on price and simplicity.

E-commerce, transactional and product-driven businesses: Klaviyo, on segmentation and revenue attribution.

That is genuinely most of the decision. The rest is detail.

Why Klaviyo costs more and where it earns it

Klaviyo's strength is tying email activity to purchase behaviour — what someone browsed, what they abandoned, what they bought, what they are likely to buy next — and reporting revenue per campaign against it.

That machinery is valuable when you have a catalogue, order history and repeat purchase patterns to work with. A service business with a booking calendar and no product data cannot feed it, so the segmentation depth sits unused while the pricing reflects it.

Why Mailchimp suits a local service list

• Cheaper at small contact counts, and free at the lowest tier
• Simple enough that a business owner can send without help
• Adequate segmentation for the two or three groups a local list actually needs
• Well-documented, with plenty of people who know it

For a list of a few hundred past customers, that is the whole requirement.

What matters more than either

Whose name the account is in. If a provider set it up under theirs, you do not control your own list.

Whether you can export. Contacts, tags and history, on demand, without asking permission.

Whether unsubscribes are handled properly. This is a legal as well as a practical matter, and what applies to your sending is worth confirming with your own adviser.

Whether anything gets sent at all. The best platform with nothing going out beats nothing, but only just.

Businesses spend afternoons comparing feature grids and then send twice a year. The platform was never the constraint.

Switching between them

Migration is usually short — export contacts, import, rebuild sequences, re-authenticate the sending domain. The risk worth managing is deliverability: rebuild your sending reputation gradually rather than pushing the full list through a new platform on day one.

Where this sits at BayouEdge

Email marketing setup is $650 a month, covering the system, welcome sequences, campaign support and list management — on your platform, in your account. The platform's own subscription is billed to you separately and stays in your name.

The honest read

If you are choosing between them for a local service business, choose Mailchimp and spend the saved afternoon writing the first sequence. If you sell products online with real purchase data, Klaviyo earns its price. Very few businesses genuinely sit between those two descriptions.
