How the field breaks down
The shortlist clustered by what you're optimising for.
The safe default
Mailchimp leads as the safest mainstream choice with easy onboarding, broad integrations, and strong brand familiarity for non-experts.
Value plays
Brevo and MailerLite deliver strong value for budget-conscious teams, combining affordability with essential features like email, SMS, and simple automations.
Specialist tools
Kit, ActiveCampaign, Klaviyo, and HubSpot serve niche needs: content creators, automation depth, ecommerce integration, or full CRM alignment.
Not on the list
AI left out Constant Contact — a tool many teams still rate. The brands AI leaves out tend to share one trait: content it can't read. Why AI snubs brands.
The contrarian pick
Kit — Often overlooked by software startups, but excellent if growth comes from content, founder-led newsletters, or community-driven audience building.
Commonly overlooked
- MailerLite
- Brevo

How to choose email marketing software
| Budget and scaling | Startups on tight budgets should consider Brevo or MailerLite. But watch out: Mailchimp and ActiveCampaign can get expensive as contacts grow. |
| Ease of use | Non-marketers gravitate to Mailchimp's approachable UI and MailerLite's clean editor. Brevo's interface may feel less refined than top premium tools. |
| Automation depth | If lifecycle automation and lead scoring matter, ActiveCampaign excels. For simpler needs, Mailchimp and MailerLite provide adequate basic automations. |
| Ecommerce fit | Klaviyo is the top choice for revenue-driven online sellers. Kit suits content-led businesses. Avoid all-in-one platforms if you only need email. |
Which should you pick?
| If you want the easiest mainstream option with broad integrations | Mailchimp |
| If you need the best budget-to-feature ratio | Brevo |
| If you are a very early startup sending newsletters and simple automations | MailerLite |
| If you need advanced lifecycle automation and segmentation | ActiveCampaign |
| If you run an ecommerce startup and care about retention revenue | Klaviyo |
| If you want email tied closely to CRM and sales operations | HubSpot Marketing Hub |
| If you grow through content, newsletters, or creator-style funnels | Kit |
