Question 1

How does BuzzBlaster work with Klaviyo?

Accepted Answer

Create a private API key in Klaviyo and paste it into BuzzBlaster. When you build a campaign you pick a list or segment and BuzzBlaster imports its recipients. It never writes back, so your flows, profiles, audiences and email sending stay untouched. Keep using Klaviyo exactly as you do now; send the SMS through BuzzBlaster.

Question 2

Will BuzzBlaster change my Klaviyo profiles or flows?

Accepted Answer

No. The API key is used to read the lists and segments you choose and import their recipients. Nothing is written back to Klaviyo: profiles, audiences, email flows and email sending are exactly as you left them.

Question 3

Why is BuzzBlaster cheaper than Klaviyo SMS?

Accepted Answer

Klaviyo and BuzzBlaster both publish credits per SMS by destination country, and ours is lower across most of Europe: Germany is 6 credits against Klaviyo's 12, Italy is 57% less, Belgium 55%. The pricing page shows every country from both rate cards. The gap varies, so check the countries you actually send to.

Question 4

How are opt-outs handled?

Accepted Answer

Every SMS ends with the word Stop and an unsubscribe link. A recipient who taps it is marked unsubscribed in your organization and skipped in every later campaign automatically. Unsubscribes are reported per campaign next to clicks and CTR.

Question 5

Does BuzzBlaster read SMS consent from Klaviyo?

Accepted Answer

No. BuzzBlaster imports every profile with a valid phone number from the lists or segments you pick; it does not read Klaviyo's SMS consent status. Manage consent by choosing consented segments in Klaviyo. BuzzBlaster enforces its own unsubscribe list on every send.

Question 6

We don't use Klaviyo. Can we still use BuzzBlaster?

Accepted Answer

Yes. Connect Shopify or WooCommerce, or upload a CSV exported from whatever runs your shop. There is no column template: BuzzBlaster finds the phone numbers, drops the invalid ones and works out each recipient's country when you create the campaign.

Question 7

Can I manage multiple brands or clients?

Accepted Answer

Yes. One login can hold several organizations, each with its own Klaviyo connection, recipients, sender name, short-link domain and credit balance. You switch between them from the menu at the top of the app. Agencies run one organization per client.

Question 8

Do I need to install anything on my website?

Accepted Answer

Not for Klaviyo or CSV. You paste an API key or upload a file inside BuzzBlaster and send from there, with no tracking script and no tag on your storefront. Connecting Shopify or WooCommerce is the one route that installs anything on the store itself.

Question 9

How do I send to several countries at once?

Accepted Answer

BuzzBlaster groups recipients by the country of their phone number and gives each country a message box with its recipient count. As you type it shows the characters, the SMS parts, the special characters pushing it over the limit, and the credit cost. Switch any country off before you send.

Question 10

What countries can I send SMS to?

Accepted Answer

29 countries in Europe: 25 of the 27 EU member states, plus the United Kingdom, Switzerland, Albania and Bosnia and Herzegovina. Cyprus and Malta are not covered. Every country has a published per-SMS credit price, shown before you send.

Question 11

What is the pricing model?

Accepted Answer

Credits cost €0.015 ex VAT. Each SMS uses 2 to 8 credits by country: Poland and Portugal 2 (€0.03), Germany 6 (€0.09), Bulgaria and Croatia 8 (€0.12). No monthly fee, minimum spend or contract. The smallest purchase is 100 credits, and credits expire 90 days after purchase.

Question 12

Will my messages show my brand name?

Accepted Answer

In most countries, yes. Set a sender name of 4 to 11 letters and numbers and it appears where the phone number would. Where a network refuses unregistered sender names, your name goes at the start of the message text instead. Links are shortened onto bzzb.io, or onto your own subdomain once you point a CNAME at us.

Question 13

Can I try it before I pay?

Accepted Answer

Yes, up to the point of sending. The account is free and takes no card. Connect Klaviyo, import recipients, build the campaign and see the exact credit cost per country before you buy anything. Each account also gets three free test SMS to your own phone. Real sends need credits; there is no free allowance.
