Email Marketing Buying Guide

Email marketing platforms should be evaluated on deliverability, automation depth, and scalability. Mailchimp leads for ease of use and generous free tier. Brevo offers strong value with email+SMS+chat in one platform. SendGrid is the developer choice for transactional email at scale. Compare pricing by contact count, not just monthly fee — the jump between tiers can be substantial.

Frequently Asked Questions

What's the best email marketing platform for e-commerce?
For e-commerce, Mailchimp offers strong Shopify/WooCommerce integrations and product recommendations. Klaviyo leads for mid-market e-commerce with deep purchase data integration. Omnisend provides excellent omnichannel automation for smaller stores.
How important is email deliverability?
Deliverability is the most critical factor — even the best-designed email is useless if it lands in spam. Look for platforms with dedicated IPs, authentication support (SPF, DKIM, DMARC), and transparent deliverability reporting. Mailchimp, Constant Contact, and SendGrid consistently rank highest.
What's a good email open rate in 2026?
Average open rates vary by industry: 21-25% for B2B, 15-20% for e-commerce, 25-30% for nonprofits. Click-through rates average 2.5-5%. Focus on list quality over size — a clean, engaged list of 10K outperforms a stale list of 50K every time.
