ActiveCampaign

ActiveCampaign is the pick when automation is the point. Its visual automation builder is the deepest here — branching logic, conditional content, lead scoring and a genuine CRM — so you can build sophisticated lifecycle journeys most tools can't. There's no free plan, but a 14-day trial lets you test it.

If your email strategy hinges on complex, behavior-driven automations and sales+marketing alignment, ActiveCampaign gives you the most control of anything in this list.
