Long welcome messages are ignored. Short welcome messages are read. A two-sentence welcome is perfect.
A IPTV reseller in Spain sends this two-sentence welcome to every new customer:
"Sentence 1: Your service is active. URL: [xxx] | User: [xxx] | Pass: [xxx].
Sentence 2: Setup guide: [link]. I reply within 30 minutes."
His Panel IPTV credentials are auto-generated. He copies them into the template. Sends. Takes 20 seconds.
A Revendeur IPTV who sends a paragraph overwhelms the customer. The customer skips most of it. Then they miss important information.
Here's what the two-sentence welcome achieved. A reseller used to send a long welcome message. Customers asked questions that were already answered in the message. After switching to two sentences, the "already answered" questions dropped by 80%.
The practical implementation is simple. Write your two-sentence welcome now. Sentence 1: credentials. Sentence 2: setup link and response promise. Save it. Use it for every new customer.
What actually works is making sentence 2 actionable. "Setup guide: [link]" is actionable. "Here's some helpful tips" is not.
I learned that customers read short messages. They skim long ones. The Two Sentence Customer Welcome is read.
Honestly, write your two-sentence welcome today. Your IPTV reseller customers will read it.
