Frequently Asked Questions

BlitzAPI FAQ

What makes BlitzAPI different from other data providers?

Most data vendors sell you bulk, unverified lists full of outdated info. BlitzAPI flips the script. We're API-first, built to integrate into your workflow. We prioritize quality and deliverability, so you only pay for verified, accurate results (not noise). Plus, our catch-all validation is next-level.

How does the "pay for verified results" model work?

Simple. You get credits. You only use a credit when we successfully return a verified piece of data you request (like a validated email or phone). If we can't find it or verify it, you don't get charged. No more wasting money on empty searches or bad data. It's fair and scalable.

Is it easy to integrate BlitzAPI into our existing tech stack?

Absolutely. We're built by devs for modern GTM stacks. Our APIs are clean, well-documented, and designed for easy integration into CRMs (like Salesforce), marketing automation tools, data warehouses, and custom apps. You shouldn't need an engineering PhD to get it running.

What kind of data coverage and accuracy do you have?

We're packing serious heat: over 360 million verified B2B contacts and 60 million enriched company profiles. Our email deliverability rate is over 98%, thanks to real-time validation tech that even tackles catch-all domains. We focus on major markets to keep our data fresh and reliable.

DeliveryNote.io FAQ

Is DeliveryNote.io really free with no catch?

Absolutely, 100% for real. There is no hidden fee, no premium tier you're forced into, and no requirement to sign up for an account. You can use it as much as you want, generate as many delivery notes as you need, and never pay a cent. We believe a tool this simple and essential should be accessible to everyone.

Do I need to create an account or download software?

Can I add my company logo and branding?

You sure can! That's one of the best parts. The tool allows you to upload your logo and input your company's name, address, and contact information. This gets saved (in your browser, not on our servers) so you can reuse it every time, ensuring every delivery note you send out is consistently and professionally branded.

What file format do the delivery notes come in?

Once you've filled in all your information, DeliveryNote.io generates a clean, print-ready document. You can then download it as a PDF file.
