Short answer: Brevo is cheapest at every size we checked for a basic newsletter, and the same holds with automations. Brevo charges by emails sent per month, not list size; Mailchimp charges by stored contacts; Klaviyo charges by active profiles, including shoppers who never opted in. At 5,000 subscribers a basic newsletter costs $32/mo on Brevo Starter, $75/mo on Mailchimp Essentials, $100/mo on Klaviyo Email. Note: with automations, Brevo wins on a plan where automations are capped; uncapped automations start at Standard (from $18/mo) on Brevo (see Key differences).

Who each is best for
Brevo is best for
Senders with a large list who email infrequently (the price follows emails sent), and businesses that also want SMS and transactional email in the same account.
- Priced by monthly email volume, not by subscribers: Starter starts at $9/mo for 5,000 emails, and each volume tier also caps how many contacts you can store (500 contacts at 5,000 emails; 500,000 from 20,000 emails). source
- Free plan sends up to 300 emails per day and keeps Brevo branding. source
- Automations are limited to 2,000 contacts on Free and Starter, and unlimited from Standard. source
- Removing the Brevo logo is a $12/mo add-on on Starter ($129.60/yr on yearly billing) and included from Standard. source
Mailchimp is best for
Small businesses that want an all-round email marketing tool with automation flows (Standard and up) and are fine with contact-based pricing and overage billing.
- Priced by stored contacts (the peak in each billing period); each tier includes a monthly send limit of 10× (Essentials), 12× (Standard) or 15× (Premium) your contacts. source
- Going over the contact or send limit on a paid plan adds overage charges rather than pausing sending. source
- Free plan: 250 contacts and 500 emails/month (250/day), no automation flows, Mailchimp branding stays. source
- Annual billing is only available through sales (Standard and Premium, 10,000+ contacts). On 2026-10-20 the page offered 15% off the first 12 months at 10,000+ contacts. source
Klaviyo is best for
Online stores (Shopify, WooCommerce and the like) that live on behaviour-triggered flows and purchase data, and accept a higher per-profile price for that.
- Priced by active profiles: everyone you can email, including shoppers who gave an email at checkout without opting in. Each tier includes 10 sends per profile a month; outgrow the tier and you move up at the next billing cycle. source
- Free plan: 250 active profiles and 500 emails a month, with flows and segmentation; Klaviyo branding stays until you pay for an email plan. source
- Self-serve billing is monthly only; annual contracts are for accounts spending $2,000+ a month. SMS and other channels are billed on top. source
