Connect Klaviyo by creating a private API key and pasting it in, then pick a list or segment. BuzzBlaster reads your recipients and never writes anything back, so your flows and audiences are untouched. Sending to Italy costs 57% less than Klaviyo's own SMS credits; Germany, 50%.
Connect the store directly, or export your recipients from whatever else you run the shop on and upload the file. There is no template to match: BuzzBlaster reads phone numbers out of any column, checks each one is a real number, and works out which country it belongs to.
BuzzBlaster sorts your recipients by the country of their phone number and gives you one box per country. As you type it shows the character count, how many SMS parts the message will be sent as, which special characters are inflating it, and the credit cost for that country. Turn any country off before you send, or schedule once and let each country receive it in its own local time.
A plain-Latin SMS fits 160 characters. One curly quote, accented letter or emoji drops the limit to 70, and a message that was one SMS becomes two parts — at twice the credits. BuzzBlaster swaps typographic lookalikes for their plain equivalents automatically, and while you are still typing it names the characters it cannot swap and shows what they are costing you.
Set a sender name of 4 to 11 letters and numbers and it shows where the phone number normally would. A few networks will not carry an unregistered name — there, your name goes at the front of the message text instead. Point a subdomain at BuzzBlaster and every link is shortened onto it; without one they go out on bzzb.io.
