SMS excels at time-sensitive, high-intent moments—order updates, short promotions, and quick confirmations. Email carries richer storytelling, longer nurtures, and catalog-style content. Most brands need both, routed by consent and customer expectation.
At GoFlux, we map journeys for company MLM programs so SMS does not cannibalize email engagement: different cadences, different creative lengths, and shared suppression rules where needed.
If you are deciding budget split, start with your margin, message complexity, and compliance posture—then test incrementally with holdout groups.
