Timing matters

Control is at your fingertips

Automated, on-time delivery

Leverage campaigns to create automated email touchpoints that build relationships on your behalf. Whether a single email or a series, let automation take the wheel so you can focus on other parts of your business.

Evergreen and predictable messaging

Maintain a consistent presence in your subscriber's inbox with regular broadcasts and keep your messaging timely and relevant, whether it's a one-time product update or an API-triggered alert.

Optimally timed, perfectly positioned

Ensure precise timing and strategic placement of your automated touchpoints and broadcasts. Customize time delays, sending constraints, and wait until qualifications to deliver content when your audience is most likely to engage.

Personalization

Advanced segmentation

Avoid sending batch and blast campaigns when you can deliver personalized messages at scale.

Group your users into segments or trigger messaging based on critical moments in your customer's lifecycle using events.
Personalize messaging with key data points such as the recipient’s first name, upcoming dates, or alternate attributes.
Display dynamic content based on a subscriber's relationship to an object.

Reporting

Assign conversion events to track the downstream impact of your email campaigns.
Clearly understand your delivery status to uncover what might prevent your emails from reaching the inbox.
Analyze email client breakdown across popular inboxes like Gmail, Yahoo, or Hotmail to enhance your content.
