What Loops is

Loops is a web-based email marketing service for sending email to a subscribed audience. Its listed tools include email automation, audience segmentation, and A/B testing, along with 20 native integrations. A free plan covers up to 1,000 subscribed contacts and 4,000 email sends in any rolling 30-day window. For audiences of 1,001–5,000 contacts, the listed price is $49 a month, billed monthly. The pricing tiers also extend through audiences of 500,000 contacts, with plans listed for each range above 5,000; the price is given only for the free tier and the 1,001–5,000-contact tier. Loops is available on the web. Its free allowance sets both a contact ceiling and a sending ceiling, while the first paid tier accommodates a larger contact list. The service brings together automated email, audience groups, and A/B testing for teams managing email campaigns. Buyers can weigh the listed contact ranges against their audience size when choosing between the free plan and paid tiers.
