When running a campaign, you may need to send boards to very large groups of contacts.
For that reason, it’s important to note that the Send feature only lets you send up to 1000 emails per day.
Many email services flag senders who send in bulk. By keeping you at a daily limit, this policy reduces the possibility your emails will get flagged or filtered by recipient email systems, ensuring all your messages arrive where they’re intended.
The limit resets each day at midnight PST. Once a new day starts, you can send additional emails.
Note: Test emails count toward the daily limit.
