Things to Keep in Mind
Direct Mail templates are created and managed in the PostcardMania app
Cadences control when mail is sent, not how it is designed
Direct Mail is most effective when used as part of a multi-channel follow-up strategy
Pro Tip ðŸ§
Start with a small test group before launching at scale. This helps validate your field mapping, cadence timing, and messaging before committing to a full campaign.
