Tools 46 found in our last check
get_accountYour account: email, credit balance, free mailbox allowance (3 on new accounts; older accounts keep 10 or 20; plus referral bonus), paid extras and your referral link.
list_mailboxesEvery connected mailbox with warm-up day, status, 7-day spam rate, today's and last 7 days' numbers, and whether it is ready for outbound.
get_mailboxOne mailbox's warm-up status and health.
mailbox_activityThe last 100 warm-up events for a mailbox (sent, received, replied, rescued from spam, errors).
warmup_statsTotals across your mailboxes: today and last 7 days (sent, received, rescued, replied), active and ready counts.
list_providersIMAP/SMTP presets (Gmail app password, Yahoo, iCloud, Zoho, Lark, SES, SendGrid, Mailgun…) with hosts and ports, plus the Google and Zoho API routes.
connect_imap_mailboxConnect any mailbox with IMAP + SMTP. The login is tested before it is saved. Use an app password when two-factor sign-in is on. Give a preset (see list_providers) or the hosts. Warm-up starts the same day.
connect_zoho_mailboxConnect a Zoho Mail mailbox through the Zoho API (works on Zoho's free plan). Needs a Self Client id, secret and a generated code from api-console.zoho.com.
google_connect_linkGet a link the user opens to connect Gmail / Google Workspace with Google sign-in (one click, any device). The mailbox appears in list_mailboxes a few minutes after they allow it.
update_mailboxChange a mailbox's display name, daily warm-up cap (1-100, null = default), time zone (IANA, e.g. Europe/London) or the signature added to its warm-up mail (empty = default: full name and company).
pause_mailboxPause warm-up for a mailbox.
resume_mailboxResume warm-up for a mailbox.
test_mailboxSign in to the mailbox now and report whether the stored login still works.
remove_mailboxRemove a mailbox and delete its stored login. Irreversible: ask the user first, then pass confirm=true.
set_pool_modeShared network (default: warm with every mailbox on the service) or private pool (only your own mailboxes write to each other; needs 2+).
set_warm_styleTeach warm-up mail how you write: paste up to 4,000 characters of your own sent emails (tone, length, sign-offs). Empty clears it. Used when the AI writes your warm-up conversations.
list_workspacesClient workspaces (agencies): each client's mailboxes are kept separate under one login and one bill. Returns id, name and mailbox count. Each mailbox in list_mailboxes has a workspace id (null = My mailboxes).
create_workspaceCreate a client workspace, e.g. the client's company name (max 100 per account).
rename_workspaceRename a client workspace.
delete_workspaceDelete a client workspace. Its mailboxes are NOT deleted: they move back to My mailboxes and keep warming. The client's report link stops working.
move_mailbox_to_workspacePut a mailbox in a client workspace. Leave workspace_id out (or empty) to move it back to My mailboxes.
get_workspace_reportThe public read-only report link for one client workspace (mailbox health, spam rate, SPF/DKIM/DMARC). The client opens it without a login; it shows no prices and nothing about other clients.
domain_healthSPF, DKIM selector, DMARC policy and MX for every domain you have connected.
check_spfLook up a domain's SPF record.
check_dkimFind a domain's DKIM key: tries the selector you give, selectors seen in real mail, then 45 common ones.
check_dmarcLook up a domain's DMARC record and policy.
get_creditsPrepaid credit balance, prices and recent charges (Outbound emails, AI drafts).
list_campaignsYour Outbound campaigns with status and stats.
get_campaignOne campaign: its emails, mailboxes, stats and time left.
create_campaignCreate a draft Outbound campaign (nothing is sent). Emails can use {first_name}, {company} and any contact field. Any connected mailbox can send; one that is still warming shows a warning first.
update_campaignEdit a paused or draft campaign. Fields you leave out keep their value.
add_contactsAdd up to 1,000 contacts to a campaign. Each needs email; other fields (first_name, company…) fill the placeholders. Duplicates and unsubscribed addresses are skipped.
list_campaign_contactsContacts in a campaign and where each is in the sequence (first 200).
start_campaignStart or resume a campaign. This SENDS real email and uses credits. Confirm with the user first. accept_sending_rules=true means the user agrees to https://emailwarmup.bobwork.ai/terms#outbound-beta (only people who may receive it, honest sender, unsubscribe honoured). If a chos…
pause_campaignPause a running campaign.
get_billing_statusPayment status after you gave the user a checkout link: credit balance, whether the extra-mailbox subscription is active, mailboxes vs the free limit, and checkouts still waiting for payment. Confirms a paid checkout straight away.
create_billing_checkoutGet a Stripe Checkout url for extra mailboxes beyond the free limit (monthly, or yearly = 10 months' price for 12). The USER opens it and pays; you cannot. Then poll get_billing_status. Returns already:true when the account is subscribed. Prices come back in the result (prices).
create_credits_checkoutGet a Stripe Checkout url to top up prepaid credits for Outbound sending and AI drafts (one-off $5, $10, $25 or $100; credits never expire). The USER opens it and pays; you cannot. Then poll get_billing_status.
list_bought_domainsDomains bought in the domain shop, their hosted mailboxes, renewal date and price, plus IMAP/SMTP settings.
search_domainsFind available lookalike domains for cold email, with first-term and renewal prices.
buy_domainsBuy domains with up to 3 mailboxes each. Returns a Stripe checkout link for the person to pay; setup starts once paid. Needs accept_sending_rules true.
add_hosted_mailboxesAdd mailboxes to a domain you bought here ($3 per mailbox per month). Returns a Stripe checkout link.
hosted_mailbox_loginPassword, IMAP and SMTP settings for one of your hosted mailboxes.
list_dns_recordsDNS records on a domain you bought here.
add_dns_recordAdd a DNS record to a domain you bought here. name = subdomain ('' for the domain itself). Types A, AAAA, CNAME, ALIAS, MX, TXT, CAA, SRV.
delete_dns_recordDelete a DNS record by id (from list_dns_records). Deleting MX, SPF, DKIM or DMARC stops the mailboxes working.
