What it can do
| Tool | What it says it does |
|---|---|
add_unsubscribe | Record an opt-out. Campaigns to that list (or every list, if list_id is empty) skip the address. |
auth | Sign up or sign in to email59. Pass email to have a 6-digit code emailed, then call again with email and otp to get a session key (a new email is signed up with 200 free emails a day). Or pass api_key to swap an API key for a session key. Send the key as the HTTP header 'Authorization: Bearer… |
block | Block an email address or a whole domain for this account. Sends to it are refused. |

Returns a checkout_url for a person to pay; the credits arrive once the… |
check_email | Free deep check of an email address, no sign-in needed: format, provider username rules, disposable and role addresses, and the domain's MX, SPF, DMARC, DKIM, MTA-STS, TLS-RPT and BIMI records. Returns a report with a score (0-99, likelihood the address is real) and a verdict (likely_valid, risky… |
check_list | List check for a mailing list: up to 1,000 different addresses a call, as emails or the text of a CSV (the column headed email). One status each: valid, risky, role, disposable, no_mx or invalid, with a reason, plus counts per status. Format, provider rules and one MX lookup per domain; no email… |
create_api_key | Create a long-lived API key (max 10 per account). It is shown only once. mode 'test' makes an e59_test_ key for staging and CI: its sends are accepted and stored, never delivered, and use no allowance. |
get_account | The signed-in account: email, daily_limit, sent_today, remaining_today, credits_remaining, resets_at. |
get_pricing | Free daily emails (renewed every day), email credits per dollar, and the packs on sale. No sign-in needed. |
list_api_keys | The account's API keys (ids and labels, never the keys themselves). |
list_blocklist | The account's blocked addresses and domains. |
list_test_messages | Emails sent with a test key (e59_test_...), newest first: accepted, stored, never delivered. Pass id for one email with its html and text (a verify_start code is in there), or to to filter by recipient. |
order_status | Status of an order from buy_pack: pending or paid. |
send_campaign | Send a marketing email to up to 1,000 recipients; the unsubscribe link is added for you. Invalid, role, blocked or unsubscribed recipients are skipped and cost nothing; each accepted recipient uses 1 email of today's allowance. A campaign that doesn't fit what's left today is refused whole. |
send_email | Send one email to one recipient: transactional (receipt, code, alert) or marketing (category). It goes out as HTML in a branded template with a text part; give text, html or both. Uses 1 email of today's allowance. Many recipients at once: send_campaign. |

validate_email | Check an address before sending. Verdicts: ok, invalid, no_mx, disposable, role. |
verify_check | Check a code from verify_start. Give to (checks the newest code sent there) or id, and code. Returns valid true or false and a status: approved, wrong_code, expired, too_many_attempts (5 wrong codes lock it), already_used, replaced or not_found. A right code works once. Uses no allowance. |
verify_start | Email a one-time verification code to an address (sign-up, sign-in, confirming an email). email59 makes the code, sends it, limits resends and expires it; the code is never returned to you. Returns an id. Uses 1 email of today's allowance. A new code to the same address replaces the one waiting… |
