Read the Q&A from Lob retail experts

Q:

How do we add direct mail to existing journeys so it runs alongside our digital channels?

Lob's API integrates directly with your CRM or CDP, so direct mail becomes another trigger in your existing journeys, not a separate workflow. When a customer hits a segment or behavior threshold, you can program mail to fire automatically to amplify your other channels.

Q:

What are the best ways to trigger winback mail, and when should it send?

Postcards work well for reactivation since they’re low-cost, easy to personalize, and can be stuck to a fridge as a reminder. Set your trigger based on lapse behavior in your CRM: typically 30, 60, or 90 days of inactivity, depending on your purchase cycle. You may even be able to reach customers that you can’t reach through email.

Q:

How do we personalize retail direct mail at scale without slowing production?

Build your template once in Lob with merge variables and conditional logic, then let your customer data do the work. Content, offers, and format can all flex dynamically at send time, whether you’re sending 500 thousand pieces or 500.
