What Every Marketer Should Know About Data Privacy in Email and SMS Marketing
Marketers who lead with explicit opt-in see up to 30% better deliverability and engagement compared to generic methods. In today’s landscape, data privacy isn’t a checkbox; it’s a competitive advantage.
Ignoring consent obligations means risking fines, losing subscriber trust, triggering spam filters, and losing revenue.
This article cuts through the noise. You’ll get four actionable tactics, real-world results, and direct implementation guidance using Yournotify.
Email vs. SMS Privacy: What You Need to Know
-
Email: Many regions allow opt-out consent (“You’ll hear from us unless you unsubscribe”), but GDPR, CASL, and PECR require explicit opt-in and proof.
-
SMS: Always requires express written consent. DND registries (like Nigeria’s) must be respected, and “STOP” responses are mandatory.
-
Recordkeeping: Log timestamp, IP, consent message, and channel, and retain it securely for audits.
The takeaway: Assume your full funnel must prove consent, and ensure systems support it.
Four Privacy-First Tactics for Immediate Wins
Each tactic ties to real results and includes a Yournotify implementation.
Tactic 1: Explicit Opt-In Design
