One Bills for Your List, the Other for Your Sends
Pick Brevo for a big list emailed rarely, and Constant Contact for a small list emailed often. Brevo also bundles automation and a CRM, while Constant Contact wins on simplicity and hands-on support. Your list size and send frequency decide which bill stays smaller.
Email is still one of the cheapest ways for a small business to reach customers. The tool you send from, though, can shape both your budget and your results. Constant Contact and Brevo take clearly different approaches to that job.
Constant Contact is a long-established name known for simple campaigns and strong support. Brevo, formerly Sendinblue, has grown by bundling email, automation, and a CRM at competitive prices. On the surface they look similar, yet they bill in opposite ways.
That billing gap is the heart of the decision. One charges for the size of your list, and the other charges for how many emails you send. Picking the wrong model can quietly inflate your monthly cost.

Small List Sent Often Versus Big List Sent Rarely
- ● Brevo bills by sends, caps contacts
- ● Constant Contact bills by contacts
- ● Match the model to your habits
Start with the pricing model, because it drives long-term cost. A contact-based plan grows as your list grows, regardless of send volume. A send-based plan grows with how many emails you send each month.
Constant Contact charges mainly by the number of contacts you store. That model suits a smaller list you email frequently, since sending more costs nothing extra. A restaurant writing to four hundred regulars every week pays the same whether it sends once a month or five times.
Brevo charges mainly by the number of emails you send, but each paid tier also caps how many contacts you can store. As of October 2026, Starter begins at $9 per month for 5,000 emails and up to 500 contacts. The free plan sends 300 emails a day and stores up to 100,000 contacts.
That model still favors a large list you email occasionally. An association with thousands of members and quarterly news can store the whole list free, though the 300-a-day cap stretches each mailing over days or weeks. On a paid plan, a list above 2,500 contacts needs at least the 20,000-email tier, whatever you actually send.
So estimate two numbers before comparing prices: your list size and your monthly send count. Those patterns favor opposite billing models, and the answer is usually obvious once both figures sit on the page.
The trade-off runs in both directions. A contact-based plan punishes list growth, and a send-based plan punishes frequency. Project a year ahead rather than a month, since either curve can bend sharply.
Events Are the Feature Gap That Often Decides It
Feature lists between these two overlap heavily, with one clear exception. Constant Contact has long bundled invitations, registration pages, and RSVP tracking with the same list you already email.
That matters more than a small monthly price difference for some businesses. A workshop, a fundraiser, or a class never needs a second platform, and the follow-up email goes to people whose attendance you already tracked.
Brevo has no direct equivalent and expects you to pair it with a dedicated event tool. For a business that runs one event a year, that is fine. For a business that runs several ticketed events, the bundling is the whole decision.
The guided templates work the same way for routine sends. Onboarding help lowers the barrier for a non-marketer, so you spend less time learning and more time sending.
Automation Depth, the Built-In CRM, and Support
Look at automation depth next. Basic tools send a welcome email or a simple sequence, while advanced tools branch on customer behavior. Brevo tends to offer deeper automation, which matters as you scale.
If you plan to automate customer journeys, Brevo gives more room to build. Behavioral triggers, segmentation, and a CRM live in one place, which reduces the number of tools you juggle as you grow.
Constant Contact can still automate the basics like a welcome series. But deeper, branching workflows are where Brevo pulls ahead, and that depth matters for a team investing in lifecycle marketing.
The trade-off is a steeper learning curve. More power means more settings to understand, so budget some setup time to use the automation well. Our best CRM for small business guide helps if you need a dedicated system instead.
Support runs the other way. Constant Contact is known for phone support and guided onboarding, while Brevo leans on email and chat. That difference is worth real money when nobody on staff troubleshoots software for a living.
The Comparison at a Glance
The table below compares Constant Contact and Brevo on the factors small businesses weigh most. Prices shift often, so it focuses on structure and features. Confirm current details on each official site, as of 2026.
| Factor | Constant Contact | Brevo |
|---|---|---|
| Pricing model | By number of contacts | By emails sent, with a contact cap per paid tier |
| Free plan | Trial, not permanent | 300 emails a day, up to 100,000 contacts |
| Automation | Basic to moderate | Moderate to advanced |
| Built-in CRM | Limited | Yes |
| Ease of use | Very beginner-friendly | Moderate learning curve |
| Support | Strong, phone available | Email and chat focused |
| Best for | Small list, frequent sends | Large list, automation |
The pattern stands out quickly. Constant Contact leads on simplicity and support, while Brevo leads on flexible pricing, automation, and CRM. Neither is simply better; they fit different senders.
Look past the headline price to the whole package. Brevo folds in automation and a CRM that might otherwise cost extra, and Constant Contact adds value through support and guided tools. Watch for add-ons too, since extra sends, premium features, or dedicated IPs change the real total.
Deliverability Is Mostly Your Own Practice
Neither vendor can be ranked reliably on inbox placement, and any article claiming a clear winner is guessing. Both are established senders with good infrastructure, and on entry tiers you share sending IPs with other customers either way.
What actually moves the needle is your own practice. Verified domain records, permission-based signups, and pruning contacts who never open do more than any platform choice.
Both offer a dedicated IP on higher tiers, which helps only once your volume is steady enough to build a reputation. Below that level it can hurt, since a cold IP has no history to vouch for it.
List hygiene pays twice on Brevo. Stale contacts damage your sending reputation, and on a paid plan they also consume sends and count toward the tier’s contact cap. Clean the list regularly to protect both results and cost.
Before You Import Your List
Decide how much automation you truly need. If a simple welcome email is enough, Constant Contact keeps things easy. If you want branching journeys, Brevo gives more headroom.
Then judge your comfort with setup. A non-marketer who wants guidance may prefer Constant Contact’s onboarding and phone help, while a hands-on team may accept Brevo’s curve for the extra features.
Test both with your own contacts before committing. Import a small segment, build a real campaign, and send it, because feature lists hide how a tool feels in daily use.
Two errors show up repeatedly. Comparing only the base price ignores the billing model that actually drives your bill, and overbuying automation you never build wastes money every month.
Finally, project a year ahead rather than to the end of the quarter. Our best accounting software small business guide helps you plan the wider tool budget. Our email marketing vs social media small business guide adds context on where email fits.
Who Should Pick Which
The table compares structure rather than deciding for you. Here is a direct call for the business shapes that most often reach this page.
The restaurant or salon emailing a few hundred regulars weekly: Choose Constant Contact. Contact-based billing means your weekly cadence costs nothing extra, and the guided templates suit an owner writing between shifts.
The association or nonprofit with thousands of members and quarterly news: Choose Brevo. Its free plan stores up to 100,000 contacts, so you avoid paying every month for members you write to four times a year. The trade-off is the 300-a-day sending cap, which paid plans remove.
The owner who wants to phone a human when something breaks: Choose Constant Contact. Phone support is a real product difference, and it is worth paying for when nobody on the team troubleshoots software for a living.
The business building behavior-based journeys: Choose Brevo. Branching on what a contact clicked or bought is where its automation clearly leads, and the built-in CRM keeps that history in one place.
The team running events several times a year: Choose Constant Contact and treat the event tools as the deciding feature. Replacing a separate registration platform usually saves more than any monthly price gap between the two.
The Rhythm Test
The decision starts with two numbers: your list size and your send frequency. Those figures point to the cheaper billing model before any feature enters the picture. Automation needs, event tools, and support style then break the tie.
Whatever you choose, confirm current pricing and terms on each official site, since plans change. Test both with your own contacts to see how each feels in practice.
Email marketing pays off most when the tool matches your rhythm. Pick the platform that fits how you actually send, and it will quietly earn its keep. For another angle, see our mailchimp vs constant contact and hubspot vs mailchimp small business comparisons.
FAQ
What is the main difference between Constant Contact and Brevo?

As of October 2026, Brevo's Starter plan begins at $9 a month for 5,000 emails and up to 500 contacts, and its free plan stores up to 100,000 contacts with 300 sends a day. A small list that emails often can be cheaper on Constant Contact, so price both at your real list size.
Which is easier for a small business with no marketing team?
Constant Contact leans toward simplicity, with guided templates, event tools, and well-known onboarding support. Brevo offers more automation and a built-in CRM but has a slightly steeper learning curve. If you want the fastest start with hands-on help, Constant Contact fits. If you want room to automate as you grow, Brevo rewards the effort.
Does Brevo really have a free plan and Constant Contact does not?

Does Constant Contact's event tool replace a separate event platform?

Which platform has better deliverability for a small sender?
Neither vendor can be ranked reliably on this, and any article claiming a clear winner is guessing. Both are established senders with good infrastructure, and on entry tiers you share sending IPs with other customers on either platform.
