Context.IO Startup Program

Are you a startup out to change the way we interact with email? We want to help you get your Context.IO powered product in the hands of a massive user base as fast as possible and lack of funds should not be stopping you. That’s why we just launched a $1 Million Context.IO Fund.

Built-in Features on All Mailboxes

Complete and easy access Quickly get metadata information about messages, attachments and contacts in the account. Fetch message bodies and attachments as needed.
API calls We don't charge per API call but we do monitor for excessive usage or abuse (intentional or not!).
Sync frequency Any API call on a mailbox will trigger a sync of our metadata index if the last one was more than 5 minutes ago.

You can also explicitly trigger a sync at any time and these calls are not metered.
WebHooks Get rule-based notifications pushed to your app through HTTP POST requests.
