Top 10 SMS Marketing Platforms

The text message marketing tools businesses use to send campaigns, alerts and automated texts, ranked by how many customers each one says it serves.

Brevo600,000+ customers 2

EZ Texting230,000+ businesses 3

Klaviyo205,000+ paying customers

Quick answer

Brevo is the largest SMS marketing platform by customers, with 600,000+, and lets you add pay-as-you-go texts from $0.0109 each to any plan, including the free one. EZ Texting is the biggest SMS-first service, used by 230,000+ businesses, and Klaviyo, with 205,000+ paying customers, is the top pick for ecommerce brands that want SMS and email from the same data.

How it's ranked: Customers, businesses or brands each vendor says it serves, as published on its own website (read November 2026). Attentive publishes no customer count, so it is ranked last with 0. Counts are each company's own claims and are measured differently (Brevo and Klaviyo count all customers, not only SMS users; EZ Texting counts businesses that have ever used it), so treat them as a guide to scale, not an audit.
