Supported Tools
validate_email
Validate Email
Validates one or more email addresses in real time to determine deliverability status.
Returns detailed information including status (valid, invalid, catch-all, unknown, spamtrap, abuse, do_not_mail), enrichment data (name, gender, location), domain details (age, MX records, SMTP provider), and optionally activity data.
For a single email, pass it directly. For multiple emails (up to 200), pass an array to use batch validation in groups of up to 100.
score_email
Score Email
Uses ZeroBounce A.I. to rate the quality of an email address, returning a score from 0 to 10 indicating how likely the subscriber is to engage.
A score of 10 is ideal, while 0 indicates a high-risk address (spam trap, inactive, etc.). Useful for evaluating catch-all emails and segmenting lists by engagement likelihood.
find_email
Find Email
Searches for a business email address by combining a person's name with a domain or company name. Tests email format patterns in real time until it finds a valid business email.
Can also discover the email format patterns used by an organization when called without a person's name.
get_account_info
Get Account Info
Retrieves the current credit balance and optionally API usage statistics for a date range.
Returns the number of remaining validation credits and, when dates are provided, a breakdown of validations performed by status and sub-status.
get_activity_data
Get Activity Data
Checks whether an email inbox has been active recently by looking at opens, clicks, forwards, and unsubscribes within the last 30 to 365+ days.
Useful for determining if an email address is currently active before sending campaigns, filtering out stale contacts.
search_domain
Search Domain
Discover a company email domain and its email address patterns using a domain or company name. Returns the primary format, confidence, and alternative formats for finding business contacts.
