Brevo vs Constant Contact: emails-sent pricing with an API, or contact pricing with phone support
Brevo and Constant Contact bill for different things. Brevo's plans start at $9 (Starter) and $18 (Standard) for 5,000 emails a month, with a free plan of 300 sends a day. Constant Contact starts at $12 (Lite), $35 (Standard) and $80 (Premium), with the final price set by your contact count and a sending cap of 10, 12 or 24 times your contacts. For a SaaS team the deciding feature is that Brevo ships transactional email and an events API on every plan.

Short answer
Pick Brevo if your product sends receipts, resets and lifecycle messages and you want one API and one bill; start on its free plan and move to Standard when you need workflows. Pick Constant Contact if you are a small business or community organization that wants live phone and chat support, events and social posting, and a contact-based price. Constant Contact is a poor fit for a software product's own transactional mail.
Plans and prices as listed
Both tables were read from the vendors' pricing pages on 7 October 2026. Brevo's amounts are the 5,000-emails-a-month starting point on monthly billing, with the yearly-billing figure that Brevo shows after a 10% discount. Constant Contact's are starting prices, with annual prepay saving up to 15%.
| Plan | Monthly | Yearly billing, per month | Notes from the page |
|---|---|---|---|
| Brevo Free | $0 | $0 | 300 emails a day, storage for up to 100,000 contacts |
| Brevo Starter | $9 | $8.08 | From 5,000 emails a month; no daily limit; no workflows |
| Brevo Standard | $18 | $16.17 | Unlimited workflows, A/B tests, web and event tracking, no Brevo logo |
| Brevo Professional | $499 | $449.08 | From 150,000 emails, 10 seats |
| Constant Contact Lite | $12 | $10.20 | 1 user, 1 automation template, sends up to 10 times contacts |
| Constant Contact Standard | $35 | $29.75 | 3 users, 3 automation templates, A/B subject lines, sends up to 12 times contacts |
| Constant Contact Premium | $80 | $68 | Unlimited users and custom automations, 500 SMS a month, sends up to 24 times contacts |
Brevo also lists Enterprise as "Starting from $2,499 per month". Sources: brevo.com/pricing and constantcontact.com/pricing.
Three sums that change the picture
- Brevo's free plan has a daily wall. At 300 sends a day, a newsletter to 1,000 subscribers takes at least four days (1,000 ÷ 300 is 3.33, so four days). The monthly ceiling is 300 × 30 = 9,000. Starter and above have no daily limit.
- Brevo's Starter is not the cheap path if you need the logo gone. Brevo's help article prices the Remove Brevo logo add-on at $9 a month, which brings Starter to $9 + $9 = $18, level with Standard, and Standard also adds workflows. The pricing page shows the add-on at $10.80, which would put Starter above Standard.
- Constant Contact's overage is small but real. A 3,000-contact list on Lite has a 30,000-send allowance. Twelve campaigns a month is 36,000 sends, so 6,000 are over, billed at $0.002 each: $12. Standard's 12 × 3,000 = 36,000 allowance would cover it. So weigh $12 of overage against the price step between Lite and Standard at your contact count.
Product and billing events
Brevo's pricing FAQ says every plan includes transactional email features: a REST API, SMTP, outbound webhooks and unlimited log retention. Its event model is open: POST /v3/events takes an event name and an identifier, and an automation can start from a Custom event trigger (Brevo events API). Brevo's Stripe page lists a Brevo API key with Zapier, n8n or Skyvia, and inbound webhooks that can create a contact or a custom event. For a trial-ending or failed-payment flow, your server or Zapier posts the Stripe event, and a Standard workflow takes over.
Constant Contact is a marketing platform: its page lists email, social tools, automation templates, segmentation and SMS, plus 300+ integrations. Its developer documentation describes partner webhooks for billing and account events, such as tier changes and cancellations, and I found no webhooks for contact activity. The Lite plan has one automation template and Standard three, so a SaaS that wants custom trial, dunning and win-back flows is steered to Premium at $80 or more, where custom automations are listed as unlimited.
Support, trial and exit terms
Constant Contact's pricing page says every plan includes live phone and chat support, and that new plans carry a 30-day money-back guarantee; its trial needs no credit card. Brevo's Free plan needs no card either, and email support is listed from Starter, with phone support from Professional. If you expect to ring someone with a question, that difference is part of the price.
Moving between them
- Export contacts with their fields and status. Constant Contact bills on contacts, Brevo on emails, so list size drives cost differently after the move.
- Import unsubscribed contacts as unsubscribed, and keep a suppression list for bounces.
- Rebuild automations by outcome. Constant Contact's templates do not transfer.
- Authenticate your sending domain in the new tool, send to your most engaged segment first, and retire the old account when the new one has sent cleanly for a week.
The decision
For a software company, Brevo is the better fit and the cheaper start: free plan, workflows from $18, transactional email included. For a local business, club or agency that wants phone support, events and social scheduling in a contact-priced tool, Constant Contact fits, with Standard at $35 as the usual starting point. If you are somewhere between, price your real monthly sends on both before you pick.

Brevo vs Constant Contact: common questions
Which is cheaper, Brevo or Constant Contact?
Brevo lists lower entry prices: $9 for Starter and $18 for Standard at 5,000 emails a month, plus a free plan. Constant Contact starts at $12 for Lite, $35 for Standard and $80 for Premium, and its page says the exact price depends on your contact count. The units differ, since Brevo charges by emails sent and Constant Contact by contacts, so run your own list size and monthly sends through both.
What does Constant Contact charge if I exceed my send limit?
Its pricing FAQ says emails still go out and additional sends are billed at $0.002 each over the monthly allowance, which is $2 for every 1,000 sends. The allowance is 10 times your contacts on Lite, 12 times on Standard and 24 times on Premium. A 3,000-contact list on Lite sending 36,000 emails in a month is 6,000 over, which is 6,000 × $0.002 = $12.
Does either one have a free plan?
Brevo does: 300 email sends a day and storage for up to 100,000 contacts. Constant Contact does not; its pricing page offers a free trial with no credit card and a 30-day money-back guarantee on new plans.
Can either send password resets and receipts?
Brevo can on every plan: its pricing FAQ says all plans include transactional email features such as a REST API, SMTP relay and outbound webhooks. Constant Contact's pricing page describes marketing email, social posting, automation and SMS, and it does not describe a transactional sending API.
