What is the best free email marketing tool?

Mailchimp's free plan covers up to 500 contacts and 1,000 sends/month — the most generous among major platforms. Klaviyo and Brevo also have solid free tiers.

What email marketing tool is best for e-commerce?

Klaviyo is the clear winner for e-commerce, especially Shopify stores. Its abandoned cart flows, post-purchase sequences, and revenue attribution are purpose-built for DTC brands.

Is email marketing still worth it in 2026?

Absolutely. Email consistently outperforms social media in both reach (no algorithm) and ROI. Owned audiences are more valuable than ever as social platforms tighten organic reach.
