In this episode of E-coffee with Experts, Austin Willman talks with Scott Cohen, CEO at InboxArmy about the real, often-overlooked mechanics behind modern retention marketing, from deliverability and DMARC to channel hierarchy (email, SMS, push), automation, attribution, and how to make AI actually useful without losing your brand voice.
Scott breaks down why email is deceptively complex (copy, design, code, deliverability, analytics), what Gmail’s stricter authentication enforcement (SPF / DKIM / DMARC) means for holiday sending, and why “spiking” volume for Black Friday can tank long-term inbox reputation.
He shares practical guidance for smaller and mid-size brands: ramp up volume gradually, rely on automations (welcome flows, cart abandons) to keep consistent daily engagement, and use channel testing (email vs SMS vs push) to learn which audiences convert where.
If you manage growth, retention, or marketing operations, this episode gives tactical, operational advice to protect holiday revenue and scale responsibly.
