The welcome flow is the highest-converting SMS sequence you'll build. It captures subscribers when intent is hottest, right after they opt in. Most brands send one welcome text and stop. The brands winning at SMS run 4 to 7 message welcome flows with discounts, content, and urgency.
A strong SMS welcome flow converts 30 to 50 percent of new subscribers to first-time buyers, often at higher conversion than the equivalent email series. Most of that conversion happens in the first 7 days after opt-in. Don't waste the window.
Subscribers from popup vs checkbox at checkout vs keyword campaigns. Each source has different intent. Build different welcome paths.
The discount code subscribers signed up for. Faster delivery means higher conversion.
Brand story, social proof, or product education. Not another discount. Build the relationship.
Discount code expiring. Adds purchase pressure without being pushy.
Set 9pm to 9am quiet hours by subscriber timezone. SMS at 6am loses you the customer permanently.
Every send needs STOP/HELP instructions on the first message. Postscript handles this if configured. Verify quarterly.
Preview in Postscript shows the message. Test send to a real phone shows the actual experience including unsubscribe footer length, MMS image quality.
Customers who buy exit welcome and enter post-purchase. Don't keep texting buyers about the welcome discount.
Record your screen while performing the postscript welcome text flow. ReccordSOP turns the recording into a SOP with timestamped screenshots. When your live setup changes, drift detection flags it.
Generate this SOP freeFour to six. Two is too few to build relationship. More than seven and unsubscribes spike.
10 to 20 percent off. SMS subscribers expect a tangible offer. Below 10 percent and conversion drops sharply.
Include one MMS (with a product image) in the flow. MMS opens at 20 percent higher rates but costs more per send.
I built ReccordSOP after watching too many DTC ops teams lose months to undocumented workflows. These SOPs are battle-tested with Shopify operators running $1M to $50M brands.
