Email Sync

Personalized email at scale

Give Bcc the boot

With Nylas, emails sync automatically in the background; no bcc or manual data entry necessary. Your users can create personalized email workflows at scale, with nearly 100% email deliverability rates.

Actionable analytics

Once the campaign is launched, your users can track email analytics such as open rate, click through rate, and replies, and pull team-wide email data to better inform their email strategy. Watch your business grow as your customer’s business grows.


Calendar Sync

Scheduling made easy

Streamline the scheduling process with a calendar API that updates in real-time. Access team level calendars to find a time that works for everyone, or send the person you're meeting with a link to your calendar, letting them choose the time that works best. As soon as an appointment slot is booked, your calendar is updated automatically, so you never miss a meeting due to being double booked.
