The Email Marketing Landscape in 2026
Email marketing delivers an average ROI of $36 for every $1 spent — higher than any other digital channel. But only if your emails actually reach the inbox. In 2026, the difference between platforms on deliverability, automation, and value is significant.
We tested seven platforms over 90 days across real campaigns. Here's what we found.
1. ActiveCampaign — Best for Automation
ActiveCampaign remains the gold standard for behavioural email automation. Its visual automation builder is the most powerful in the market, letting you create multi-branch sequences triggered by any combination of user actions.
Best for: B2B SaaS, e-commerce brands, and any business with complex customer journeys.
Pricing: From $29/month (500 contacts).
2. Klaviyo — Best for E-Commerce
Klaviyo has become the default email platform for Shopify and WooCommerce stores. Its native integrations with e-commerce platforms are deeper than any competitor, with pre-built flows for abandoned cart, browse abandonment, and post-purchase sequences.
Best for: Online stores doing over £5k/month in revenue.
Pricing: Free up to 250 contacts; scales with list size.
3. Mailchimp — Best for Beginners
Mailchimp's brand recognition and ease of use make it the natural starting point for email marketing beginners. The free tier supports up to 500 contacts and 1,000 monthly sends — enough to get started.
Best for: Small businesses just starting with email marketing.
Pricing: Free tier available; paid from $13/month.
4. Brevo (formerly Sendinblue) — Best Value
Brevo charges by email volume rather than list size, making it exceptionally cost-effective for businesses with large lists but moderate sending volumes. 20,000 emails/month costs just $25.
Best for: Businesses with large lists who send infrequently.
Pricing: Free up to 300 emails/day; paid from $25/month.
The Verdict
For most businesses starting out: Brevo (best value) or Mailchimp (easiest setup). For e-commerce: Klaviyo. For B2B with complex automation needs: ActiveCampaign.
