Top picks reviewed

#1

ActiveCampaign

4.5

ActiveCampaign is what small teams buy when email automation becomes the growth engine. Its journey builder handles branching logic, site tracking, lead scoring and a built-in sales CRM, at a price far below enterprise marketing clouds. Deliverability consistently benchmarks well. The learning curve is real — its power lives in a dense interface — and there is no free plan, so it fits businesses ready to invest in automation rather than dabble.

Pros

  • Best-in-class automation
  • Good deliverability
  • Built-in CRM

Cons

  • Learning curve
  • No free plan
