The library
Email 101: the open channel people keep
Email is the one business channel nobody owns: it runs on open standards, reaches more than four billion people and holds the records customers keep. Whether a message lands in the inbox depends on proving who sent it, keeping complaints low and respecting consent rules that differ by country.
WeChat 101: official accounts, mini programs and WeCom
How businesses use WeChat's Official Accounts, Mini Programs and WeCom, what verification costs, the messaging limits and Chinese data rules that come with them, and when WeChat is worth adding.
Voice 101: business phone calls, numbers and caller-ID trust
How a business phone call travels between the phone network and the internet, what numbers, SIP and IVR are, what calls cost, and the caller-ID and robocall rules that decide whether anyone answers.
Sender registration around the world: who you have to tell before you text
Why countries regulate who may send business messages, what you usually have to register, and how the rules differ across the US, Canada, Europe, India, Brazil, the Gulf, Singapore and Nigeria.
