AMP for Email (Accelerated Mobile Pages for Email) allows users to interact with dynamic content — fill forms, browse carousels, confirm bookings — directly inside the inbox without opening a browser. It dramatically increases engagement and conversion rates. Postera is one of the few agencies with native AMP email development capability.
Zero-knowledge authentication means verifying a subscriber's identity without transmitting or storing their password or sensitive credentials. Instead of a login link that exposes data, we implement cryptographic proofs that authenticate users invisibly inside the email flow — dramatically reducing security risk and increasing compliance with GDPR and HIPAA.
Email deliverability depends on four pillars: technical authentication (SPF, DKIM, DMARC, BIMI), IP and domain reputation, list hygiene, and content quality. Postera's audit process covers all four. We identify exactly where inbox placement is failing and implement a structured warmup and monitoring plan to achieve 95%+ inbox rates.
BIMI (Brand Indicators for Message Identification) is an email authentication standard that displays your verified brand logo in recipients' inboxes. It requires a valid DMARC policy at enforcement level and, for major inbox providers like Gmail, a Verified Mark Certificate (VMC). BIMI increases open rates by 10–20% and signals brand legitimacy to inbox algorithms.
A Customer Data Platform (CDP) — like Segment or RudderStack — is a unified database that collects behavioural, transactional, and demographic data from all your touchpoints. Postera builds connectors between your CDP and your email delivery platform so that every send is powered by real-time, first-party data — not stale CRM exports.
