FAQ
Is there a free SMS marketing tool?
Klaviyo offers a free tier that includes a monthly allowance of SMS/MMS sends, making it a common starting point for small ecommerce stores. Most dedicated SMS platforms carry per-message or per-segment carrier fees, so factor message volume into any cost comparison.
Do I need consent to send marketing texts?
Yes. In the US, laws like the TCPA require explicit opt-in consent before sending marketing SMS, plus a clear way to opt out (usually replying STOP). Reputable platforms build consent capture, opt-out handling, and quiet-hours compliance into their tools.
Should I use SMS or email marketing?
Use both. Email is better for longer, richer content and costs little per send; SMS drives high open rates for short, time-sensitive messages like drops, restocks, and shipping updates. Platforms like Klaviyo and Attentive let you run them together and coordinate the two channels.
