The verdict Side by side Plans and pricing Who each is for Other options

The verdict

For a small B2B team that wants email, a text follow-up and a simple contact record without paying for three tools, I'd pick Brevo. It covers more channels, it has an official MCP server for AI clients, and pricing by volume tends to suit a growing list.

If you are an agency sending for several clients, or a small team where the look of every email matters and you want clear reports, I'd pick Campaign Monitor.

If you need deep lead scoring or CRM-driven automation, neither is the answer, and a platform such as HubSpot fits better. Whichever you lean towards, model the cost at the list size and sending you expect in a year, not the ones you have today.

Who each is for

Choose Brevo if…

Brevo suits a lean B2B team that feels the split between its email tool, its SMS tool and its CRM. One automation can send an email, follow up with a text and create a task for sales. It also suits a team that sends system emails and wants the transactional API in the same account as its marketing.

Expect limits. The CRM is basic, and A/B testing and landing pages sit on higher plans, so the entry plans can feel tight as you grow. Pick it for breadth and simple automation, not for advanced segmentation.

Choose Campaign Monitor by Marigold if…

Campaign Monitor suits agencies sending for several clients, solo marketers and small businesses that want on-brand emails without a developer. The template builder is aimed at people who are not designers, and the dashboards show how each campaign performed.

Marigold owns it, so ask what your plan includes and what is sold as a separate product. The vendor shows a free plan next to a trial, so check what the free plan allows before you import a list. It has an API but no official MCP server, so AI-driven work goes through the API.
