Email marketing that brings customers back

Email can return $36 for every $1 spent. Per Diem helps restaurants turn customer and order data into targeted, branded emails that give people a reason to order again.

Better emails start with customers you already know

Choose recipients: all customers, customer groups or behavior-based segments, sending to 449 customers
Every order gives you more customer data to work with. Reach everyone, build your own groups, or target segments that update as customer behavior changes.

Build the journey from first order to VIP

VIP automation: send a personal email at 1.5x a regular's usual gap, then a perk by push at 2.5x
Coming soon
Use customer behavior to trigger the right emails at the right stage, from welcoming a new customer to bringing them back, rewarding regulars, and growing them into VIPs.

Turn a campaign idea into an email worth opening

You don't have to spend an afternoon turning a promotion into an email. Start with a prompt, reuse a template, or build with custom HTML, then make the campaign look and sound like your restaurant.
