Email marketing tools are deceptively hard to choose because they look similar at a glance and reveal their real differences only in the pricing P&L and the automation builder. This page is our hub for every email-marketing comparison we've actually run. Below the grid is the decision framework we apply, so you can match a platform to your stage and sends before jumping into the head-to-head detail pages.
How to choose: the framework we use
Most "which email tool" questions collapse into three gating factors:
- Your sending volume vs the free tier. Every platform's free tier caps contacts, sends or both. If you're under ~5,000 contacts with modest sends, the free tier often IS the recommendation — and the decision becomes which free tier is genuinely usable, not just which is biggest.
- Automation depth you actually need. Marketing-automation tools (ActiveCampaign) outpace email-sender tools (Mailchimp, Brevo) on triggers, scoring and CRM-style journeys. But depth is useless if your team won't use it. Match complexity to the person who'll build it.
- Deliverability and compliance features. Clean list management, SPF/DKIM/DMARC handling and spam-compliant unsubscribe flows matter more at scale than any feature list. We weigh these heavily in every verdict.
Each comparison below applies this framework with our hands-on notes. Start with the page matching your contact volume and team, then read the closest alternative.
