Anyone running a print and mail operation through Poplar is used to juggling two channels at once, a physical piece dropping into a letterbox and a faster nudge that lands on a phone. Growth and lifecycle teams who lean on Poplar to validate a US postal address, create a mailing from a physical address, or add a new member to an audience already have the data on hand to trigger a text at the same moment, using the Zapier connection between the two apps.

A customer replying to a text to opt out of contact should not need to be tracked in two separate places by hand. That reply can automatically add the person's details to Poplar's do not mail list, so mail suppression stays in step with what the customer just asked for by text, and nobody has to update a second list themselves later in the day.

Address validation also earns its keep earlier in a Zap. When an order is paid for in Shopify or a form response comes in, Poplar can validate the address on the way through, and once it checks out, Mobile Message can send a text confirming shipping details or next steps. The mail side gets a clean address, the customer gets a text, and nobody has to check either one by hand.
