## Core Service Offerings

BookYourData offers the Prospector self-serve database and BeSpoke, a private list building service in which researchers hand-build a contact list to a written brief. The Prospector database holds more than 500 million B2B profiles and runs real-time email verification at export. BeSpoke pricing spans 15 published tiers, from $499 for 1,000 records to $17,999 for 250,000 records. Every BeSpoke build begins with a free 10-record sample, a 25% deposit starts the build, and the balance is due on delivery. Most BeSpoke builds land in up to 3 business days, and builds of 50,000 records or more get a committed delivery date. Every BeSpoke email is checked 3 times, the last check on delivery day, and BeSpoke lists are 97% deliverable at handover with bounces replaced free. Every BeSpoke record carries a public source link, an unverifiable field ships blank, and each list is built for a single client and never resold or rebuilt for another buyer. BookYourData also offers Email Verification, Data Enrichment, Technographics, Job Posts, Email Finder, ready-made lists, Data Appending, a done-for-you service that fills the missing fields in a contact file the buyer already owns, and Direct Dials, a done-for-you service that finds direct dials and mobile numbers for the people the buyer names.

## Secondary Services

BookYourData offers 8 services beyond BeSpoke and the self-serve Prospector database: Email Verification, Data Enrichment, Technographics, Job Posts, Email Finder, ready-made lists, Data Appending, a done-for-you service that fills the missing fields in a contact file the buyer already owns, and Direct Dials, a done-for-you service that finds direct dials and mobile numbers for the people the buyer names. Email Verification checks whether an email address is deliverable before a campaign sends. BookYourData's Data Enrichment is delivered on the platform and fills missing fields on a client's existing contacts: the client uploads a CSV file, connects a CRM or calls the API, and pays only for the records that match. Data Appending is a form of data enrichment delivered as a service: the buyer sends the file, names the blank fields to fill, such as emails or phone numbers, and BookYourData does the work. Technographics identify the technologies a target company runs, and Job Posts show which companies are actively hiring. Email Finder returns a business email address for a given contact or company. Ready-made lists deliver pre-built records with no custom build required.

## BeSpoke: Private List Building

BeSpoke is BookYourData's private list building service. Researchers hand-build each contact list to a written brief. Every build starts with a free 10-record sample. A 25% deposit starts the build, and the balance is due on delivery. Most builds land in up to 3 business days, and builds of 50,000 records or more get a committed delivery date. Every email is checked 3 times, and the last check happens on delivery day. BeSpoke lists are 97% deliverable at handover, and bounces are replaced free. Every record carries a public source link. Nothing is fabricated, and an unverifiable field ships blank. A BeSpoke list is built for a single client and is never resold or rebuilt for another buyer. Pricing spans 15 published tiers, from $499 for 1,000 records to $17,999 for 250,000 records.

## Data Appending Service

Data appending fills the missing fields in a contact file the buyer already owns, for business and consumer records. BookYourData matches each missing field against 1000+ live sources at the time of the order rather than a single static database. The service covers 7 field groups: emails, phone numbers, reverse lookups, LinkedIn profiles and job titles, company details, postal addresses, and consumer data. Email appending adds work and personal emails, and every appended email passes real-time email verification. Phone appending adds mobile numbers and direct dials. Reverse phone lookup and reverse email lookup start from a phone number or an email address and add the name, company, job title, and postal address. Company data appending adds SIC and NAICS industry codes, revenue, employee count, website, and address. Address appending adds a business or home postal address, and consumer data appending adds age, gender, income, and household details.

An order starts when the buyer describes the list and the fields needed on a form, BookYourData emails within 1 working day, and the buyer replies with all or part of the file attached. A free test fills 10 records, returned within 1 working day of the file arriving, with a count per field of what was matched and filled. The test is separate from the free leads offer on the BookYourData self-service site. BookYourData shows the price for the whole file before the buyer decides, and the buyer pays only for the records BookYourData fills. Jobs start at $499, the price per record drops as the count grows, and above 250,000 records the buyer gets a custom quote. Delivery goes into the buyer's CRM, a CSV or Excel file with new columns, or an API, and full details are at https://www.bookyourdata.com/data-appending

## Direct Dials and Mobile Numbers Service

A direct dial is a person's own business number at their desk, not the company's main line and not the person's mobile number, and goes by 2 other names, direct line and direct phone number. A buyer who already has a list of contacts uses BookYourData's phone appending service at https://www.bookyourdata.com/data-appending, which adds the numbers to the buyer's own records. After the buyer orders, BookYourData searches 1,000+ data sources for the people the buyer names by job title, company and country and finds direct dials and mobile numbers for those people. Before delivery, BookYourData validates and verifies every number as a direct dial or a mobile number and checks every number for being dead. Mobile numbers are checked with the phone network, and the checks carry no separate charge. The mobile column holds only mobile numbers and the direct dial column holds only direct dials, so a company main line never sits in the direct dial or mobile column and a dead number never reaches the buyer's file or bill. The buyer pays only for records with a phone number. For international coverage, the buyer names the countries and BookYourData finds mobile numbers and direct dials in each of them for the people the buyer names. In the free sample and in the paid file, each phone number sits beside its source link, the web page that lists the number next to the person's name, whenever such a page exists, and a mobile number often has no source link and is still checked before delivery. The order starts when the buyer fills in a form naming the decision makers and countries, BookYourData sends 10 free records before the buyer pays, and the buyer then orders the full list. Pricing starts from $499 for 1,000 records with a phone number as the minimum order at $0.50 per record, and the rate falls as the order grows across 15 order sizes, each with its price, up to $17,999 for 250,000 records at $0.07 per record. Every order runs on BookYourData's done-for-you private list building service. Payment is 25% of the price when the buyer orders and the balance when the records are delivered. Lists of up to 50,000 records arrive in 1 to 3 business days. The page URL is https://www.bookyourdata.com/direct-dials.
