{"activeVersionTag":"latest","latestAvailableVersionTag":"latest","collection":{"info":{"_postman_id":"93a0be7c-ee2f-451d-aae8-514d9f159d03","name":"hygiene.email","description":"# **Glossary**\n\n#### **RECOMMENDATION**\n\n**safe_to_send**: Email address is deliverable and has low-to-no threats detected.\n\n**send_with_caution**: The email address is possibly deliverable or has an elevated threat level.\n\n**do_not_send**: Email address is undeliverable or high threat level detected.\n\n#### **RATING**\n\n**excellent**: Email address is deliverable, with no known threats detected.\n\n**good**: Email address is deliverable, with a low threat level detected.\n\n**fair**: Email address is deliverable, with a low-to-moderate threat level detected.\n\n**poor**: Email address is possibly deliverable or moderate-to-high threat level detected.\n\n**bad**: Email address is undeliverable or high threat level detected.\n\n#### **SCORE**\n\nAll emails are scored for quality on a 1 through 10 basis, with 10 having the best overall quality and 1 having the worst.\n\n| Score | Description |\n| --- | --- |\n| 10 | Deliverable, no known threats detected |\n| 9 | Deliverable, low threat level detected |\n| 8 | Deliverable, catch-all domain, low threat level detected |\n| 7 | Deliverable, low-to-moderate threat level detected |\n| 6 | Possibly deliverable, disposable domain, catch-all or unknown, mailbox full; low threat level |\n| 5 | Possibly deliverable, disposable or catch-all, unknown or role-based; moderate threat level |\n| 4 | Possibly deliverable, disposable or catch-all, unknown or role-based; high threat level |\n| 3 | Undeliverable, mailbox disabled |\n| 2 | High threat level, dangerous contact |\n| 1 | High threat level, malicious contact |\n\n#### **STATUS**\n\n**deliverable**: A deliverable result means the recipient's mail server stated the recipient exists.\n\n**possibly_deliverable**: Possibly deliverable means that the address has quality issues that may result in a bounce or low engagement. Classifications include Catch-all, Disposable, and Role-based addresses; therefore, use caution when sending to addresses that are possibly deliverable.\n\n**undeliverable**: An undeliverable result means the email address does not exist or is syntactically incorrect (and therefore does not exist).\n\n**unknown_deliverability**: Alfred will return an unknown result when it could not get a response from the recipient's mail server. This happens when the destination mail server is too slow or temporarily unavailable. In some cases, retrying your request after about 5 minutes will return a valid or invalid response. Unknown addresses don't count against your credits.\n\n#### **REASON**\n\n##### deliverable:\n\n**accepted_email**: Email address was accepted by the SMTP server.\n\n##### possibly_deliverable:\n\n**catch_all**: Some domains accept all emails you send to them, even if the email address is not valid. We classify these addresses as \"catch_all\". After an email is sent, the recipient mail server may silently discard the message or send a bounce message after the fact. In these cases, Alfred cannot guarantee an email will be delivered to a user's inbox. Sending to an Accept All domain may increase your bounce rates and lower your open rates. Therefore, use a degree of caution when sending to catch-alls.\n\n**disposable**: Email addresses that point to domains like spamgourmet.com and mailinator.com are disposable email services. These services enable users to create one-time email addresses to receive initial communications from a service (such as an activation email or coupon) which are then discarded. It is highly recommended you do not mail to disposable email addresses.\n\n##### **undeliverable:**\n\n**invalid_email**: Specified email is not a valid email address syntax.\n\n**invalid_domain**: Domain name does not exist or is not configured to receive email.\n\n**rejected_email**: The email address was rejected by the SMTP server; the email address does not exist.\n\n##### unknown_deliverability:\n\n**dns_error**: We could not resolve the DNS records, or the domain is misconfigured.\n\n**unavailable_smtp**: The SMTP server was unavailable to process our request.\n\n**unknown**: An unexpected error has occurred.\n\n##### other:\n\n**role_based:** A role email is an address that's typically associated with a function (postmaster, support, sales, etc.) instead of a person. In some instances, mailing to a role address can lead to a decreased open rate and is generally advised against while sending marketing emails.\n\n**mailbox_disabled**: Email address exists but is disabled and won't be able to receive email.\n\n**mailbox_full**: The inbox of this recipient is full, it might generate a soft bounce.\n\n**suspicious**: Email address appears to be system or non-human-generated bots.\n\n**dangerous**: Domain and address associated with consistent negative engagement.\n\n**malicious**: Domain and address associated with elevated negative engagement.\n\n#### **THREAT LEVEL**\n\n**undetermined**: No known threats were detected, and the risk to mailing reputation is unknown.\n\n**low**: Email address is widely circulated; risk to mailing reputation is low.\n\n**moderate**: Email address is widely circulated, non-human generated, identified in a data breach, or associated with negative engagement; risk to mailing reputation is moderate.\n\n**high**: Email address is associated with dangerous or malicious contact or domain; risk to mailing reputation is high.\n\n---\n\n# **API**\n\n## **Getting Started**\n\nBase URL:
