FAQ
Email & SMS FAQ
What does an email & SMS marketing agency do?
An email & SMS agency plans, builds and runs a brand's retention program: automated flows, campaigns, list growth and segmentation. Bolstered Media does this for DTC and ecommerce brands on Klaviyo and Attentive.
Which email and SMS platforms do you work with?
Klaviyo and Attentive. Bolstered Media is an official partner of both, and an official Shopify partner.
Should we use email, SMS or both?
For most DTC brands, both, planned together: email for depth and storytelling, SMS for timely, high-intent messages. The right balance depends on your list and customers, which we map on a strategy call.
Do you also run paid ads?
Yes. Facebook & Instagram ads management is our other core service, so the customers you acquire flow straight into your retention program.
How is email & SMS management priced?
Every engagement is custom. We offer Performance-Based or Flat-Fee options, and scope ranges from Consulting to Full Done-For-You. We don't publish a price list; we scope the right fit with you on a strategy call.
