Frequently Asked Questions
viaSocket connects LettrLabs to your other business apps so handwritten, personalized direct mail is automatically triggered by real customer events—such as a new order, an abandoned cart, or a lapsed customer status.
You can connect common CRMs, ecommerce platforms, form tools, and data sources to LettrLabs through viaSocket. This lets you send handwritten mail based on activity in the tools you already use to manage leads and customers.
viaSocket can use AI to draft unique, human-sounding note copy using each customer’s history, segment, or activity. That AI-generated text is then passed to LettrLabs, which turns it into real handwritten mail at scale.
No. viaSocket is built for non-technical teams. You define simple rules like “when this happens in my CRM, send data to LettrLabs,” and the workflow runs in the background without custom code.
Automating LettrLabs through viaSocket helps you recover more abandoned carts, improve winback and retention campaigns, and strengthen relationships with high-value customers—while saving time compared to running manual direct mail lists.
