Audience Segmentation
Personalized messaging drives higher open rates and conversions. By knowing a contact’s gender, you can tailor subject lines, salutations, and product recommendations. RealValidito’s gender lookup enriches your CRM with gender data so every campaign speaks directly to each customer — improving engagement and reducing unsubscribes.
Validate Real Names
Fake, random, or offensive names degrade data quality and skew campaign results. RealValidito’s gender lookup flags names that lack any recognized gender association, helping you identify and remove invalid entries before they pollute your database or reach your outreach sequences.
Clean Your Database
A clean database starts at the point of capture. Integrating gender lookup into your web forms ensures that only valid, recognizable names are accepted — preventing junk entries like “asdfgh” or “xxxxx” from ever entering your system. Run bulk validation on existing records to remediate historical data in one pass.
How Gender Lookup by Name Works
1 Submit a First Name
Enter any first name into RealValidito’s gender lookup tool or pass it via the API. Enter a first name or the full name: titles (Mr, Dr), initials and suffixes (Jr, III) are skipped, and the first name decides.
2 Query RealValidito Gender Lookup API
Your application passes the first name to the RealValidito Gender Lookup API. The API skips titles, initials and suffixes and takes the first name.
3 Cross-Reference Name Database
RealValidito compares the first name with about 3.5 million first names used in the United States and Canada.
4 Return Gender & Name Status
Each valid first name returns Male, Female or Unisex. Names that are offensive are flagged as salacious, and entries that are not real first names (keystrokes, words, company names) are flagged as random. Your application can then personalize communications, flag invalid entries, or route records for manual review.

What is gender lookup by name?
Gender lookup by name is the process of predicting the likely gender of a person based solely on their first name. It works by comparing the name against a large database of first names. The gender shows how often a name is given to men or women — it says nothing about the person.
How accurate is RealValidito’s gender detection?
Results depend on the name: common first names are well covered, while rare or very unusual spellings may be missing and are then reported as random. If a real first name is reported wrongly, send it to us and we will check it.
What data does the gender lookup API return?
For each name the API reports a valid first name with its gender (Male, Female or Unisex), a salacious (offensive) name, a random entry (not a real first name) or an incomplete name. This structured JSON response can be consumed directly by CRM systems, marketing platforms, or custom back-end applications.
Can I look up gender for non-English names?
Yes, as far as they are used in the United States and Canada: Gender Lookup covers about 3.5 million first names, including many names of international origin. Rare names may be missing — send them to us and we will check them.
How do I integrate the gender lookup API into my application?
Send an HTTP POST request with your API key, API secret and up to 1,000 names; the API answers in JSON. Full documentation is available at realvalidito.com/api.
Is the gender lookup tool free to use?
Yes — new accounts receive 1,000 free gender lookup credits with no credit card required. After your free credits are used, you buy only the lookups you need — the price per lookup goes down with larger packages. There is no monthly or fixed subscription.
What is the difference between gender lookup and gender detection?
The terms are used interchangeably. Both refer to inferring gender from a first name rather than from self-reported demographic data. Names that are given to both men and women, like “Jordan”, “Alexis” or “Sam”, are reported as Unisex.
Can I use gender lookup to clean my email list?
Absolutely. The bulk gender lookup feature accepts CSV uploads containing first names. You can identify invalid, offensive, or unrecognizable names alongside gender assignment — effectively combining list cleaning with personalization enrichment in a single pass.
Does gender lookup work with middle names or full names?
Yes. Titles (Mr, Dr …), initials and suffixes (Jr, III) are skipped, “Smith, John” is read as John, and only the first name decides. For best results, send the first name field separately.
How is RealValidito different from other gender lookup APIs?
RealValidito combines gender detection with name validation: offensive names are flagged as salacious and entries that are not real first names as random, instead of being given a gender.
