Best Email Marketing Software in 2026

Mailchimp was founded in Atlanta in 2001 as an alternative to the expensive email software of the time and serves what it describes as millions of customers. Intuit completed its acquisition of the company on 1 November 2021 for about US$5.7 billion in cash and some 10.1 million Intuit shares valued at roughly US$6.3 billion. Mailchimp offers four plans priced by contact count. The Free plan is limited to 250 contacts and 500 sends per month (250 per day). At the time of review the paid plans were shown with a 50% discount for the first 12 months, from US$13 per month for Essentials, US$20 for Standard (up to 6,000 emails per month at the lowest tier) and US$350 for Premium (up to 150,000 emails), with the post-promotion price depending on contact count. Its integration with Intuit's QuickBooks is a distinguishing feature for small businesses already using that accounting software.

Klaviyo was founded in 2012 by Andrew Bialecki and Ed Hallen as a customer database for consumer brands and added email marketing the following year; it now describes itself as a B2C CRM combining marketing automation, analytics and customer service, with its global headquarters in Boston. Pricing is based on active profiles. The Free plan covers up to 250 active profiles and 500 emails per month; the Email plan starts at US$20 per month for 500 active profiles and 5,000 emails; and the Marketing plan, which adds SMS and other channels, is listed at US$25 per month with a limited-time offer of a first month for US$1. Accounts with more than 150,000 active profiles are priced by sales. Its use of customer and purchase data for segmentation makes it a common choice for online retailers.

Brevo, previously named Sendinblue, was founded in 2012 by Armand Thiberge in India and France and reports 600,000 customers. Unlike most competitors, it prices mainly by the number of emails sent rather than by contacts stored. The Free plan allows up to 300 emails per day once an account is approved for sending. Paid plans listed in the page's structured data are Starter at US$9 per month (from 5,000 emails per month), Standard at US$18 per month, which adds marketing automation and A/B testing, and Professional at US$499 per month (from 150,000 emails); yearly billing reduces prices by 10%. The platform also includes transactional email, SMS, chat and a sales CRM, so organisations with large contact lists but modest sending frequency often find it cheaper than contact-based tools.

Pro adds features such as a newsletter referral system using SparkLoop. Kit's emphasis on monetisation tools distinguishes it from general small-business email services.
