What happens during your first sync
The first sync reads your most recent email so the AI secretary can build your Action Items, Highlights, and FYIs. Items start appearing within a few minutes, and older mail keeps loading in the background. How far back the first sync reaches depends on your plan, and you get a notification when it finishes.
How the first sync works
When you connect an account, MailOver fetches your most recent email and the AI secretary starts reading it. For each message it writes a short title and summary, then sorts it into Action Items, Highlights, and FYIs. The work runs in parallel batches rather than one message at a time, so things move quickly. You can keep using MailOver while it runs.
Action Items, Highlights, and categories start showing up within a few minutes. The rest of your recent mail keeps loading in the background, so your view fills in steadily after that.
How far back it reads
The first sync covers your most recent messages, and how many depends on your plan. Free reads the last 60, Plus the last 200, Pro the last 500, and Ultra the last 2,000. After this initial sync, MailOver keeps up with new mail as it arrives, in near-real-time for Gmail and on a short polling cycle for Outlook and IMAP.
Each email the AI processes uses one credit. So a first sync on the Plus plan that reads 200 messages uses up to 200 credits. Your daily processing also has a cap that scales with your plan, which keeps a busy mailbox from burning through everything at once.
When it is finished
When the first processing run completes, you get a push notification so you do not have to keep checking. It looks like this:
Your first daily brief follows a few minutes after that. For more on what it contains, see Read your first daily brief.
