Email plans: contact limits vs. send limits
How to compare email audience sizes and sending allowances.
Most email plans cap two things, how many contacts you can store and how many emails you can send. The second one is easier to miss.
Note the time period
Brevo Free caps sending per day, while MailerLite Free sets a monthly allowance. You can't treat a daily cap as a monthly pool, because the size and timing of each campaign matter. Kit Free allows unlimited broadcasts but caps subscribers.
Work out your own numbers
If you have 1,000 subscribers and send four newsletters a month, that's 4,000 sends before any welcome emails or other automations. Check that number against both the audience limit and the sending allowance, plus any daily cap.
Watch for separate limits
Stored contacts, subscribers, automation contacts, and paid-tier audience sizes are separate limits. A paid plan's starting price can cover fewer contacts than the free plan. Always note which tier a number belongs to.
