Nothing serious here today

Today is the operative word: we check Emailwarmup every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 45

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

campaign

create_campaign

Create 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.

get_campaign

One campaign: its emails, mailboxes, stats and time left.

list_campaign_contacts

Contacts in a campaign and where each is in the sequence (first 200).

update_campaign

Edit a paused or draft campaign. Fields you leave out keep their value.

mailbox

get_mailbox

One mailbox's warm-up status and health.

mailbox_activity

The last 100 warm-up events for a mailbox (sent, received, replied, rescued from spam, errors).

remove_mailbox

Remove a mailbox and delete its stored login. Irreversible: ask the user first, then pass confirm=true.

update_mailbox

Change a mailbox's display name, daily warm-up cap (1-100, null = default) or time zone (IANA, e.g. Europe/London).

dns

add_dns_record

Add 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_record

Delete a DNS record by id (from list_dns_records). Deleting MX, SPF, DKIM or DMARC stops the mailboxes working.

list_dns_records

DNS records on a domain you bought here.

workspace

create_workspace

Create a client workspace, e.g. the client's company name (max 100 per account).

delete_workspace

Delete a client workspace. Its mailboxes are NOT deleted: they move back to My mailboxes and keep warming. The client's report link stops working.

get_workspace_report

The 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.

billing

create_billing_checkout

Get 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).

get_billing_status

Payment 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.

connect

connect_imap_mailbox

Connect 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_mailbox

Connect 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.

credits

create_credits_checkout

Get 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.

get_credits

Prepaid credit balance, prices and recent charges (Outbound emails, AI drafts).

hosted

add_hosted_mailboxes

Add mailboxes to a domain you bought here ($3 per mailbox per month). Returns a Stripe checkout link.

hosted_mailbox_login

Password, IMAP and SMTP settings for one of your hosted mailboxes.

pause

pause_campaign

Pause a running campaign.

pause_mailbox

Pause warm-up for a mailbox.

account

get_account

Your account: email, credit balance, free mailbox allowance (10, or 20 for accounts created before 27 October 2026, plus referral bonus), paid extras and your referral link.

bought

list_bought_domains

Domains bought in the domain shop, their hosted mailboxes, renewal date and price, plus IMAP/SMTP settings.

buy

buy_domains

Buy 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.

campaigns

list_campaigns

Your Outbound campaigns with status and stats.

contacts

add_contacts

Add 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.

dkim

check_dkim

Find a domain's DKIM key: tries the selector you give, selectors seen in real mail, then 45 common ones.

dmarc

check_dmarc

Look up a domain's DMARC record and policy.

domain

domain_health

SPF, DKIM selector, DMARC policy and MX for every domain you have connected.

domains

search_domains

Find available lookalike domains for cold email, with first-term and renewal prices.

google

google_connect_link

Get 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.

mailboxes

list_mailboxes

Every 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.

move

move_mailbox_to_workspace

Put a mailbox in a client workspace. Leave workspace_id out (or empty) to move it back to My mailboxes.

pool

set_pool_mode

Shared network (default: warm with every mailbox on the service) or private pool (only your own mailboxes write to each other; needs 2+).

providers

list_providers

IMAP/SMTP presets (Gmail app password, Yahoo, iCloud, Zoho, Lark, SES, SendGrid, Mailgun…) with hosts and ports, plus the Google and Zoho API routes.

rename

rename_workspace

Rename a client workspace.

resume

resume_mailbox

Resume warm-up for a mailbox.

spf

check_spf

Look up a domain's SPF record.

start

start_campaign

Start 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 chosen mailbox is still warming the call fails with warming:true; show the user the message and set accept_warming_risk=true only after they explicitly agree. Without credits it fails with credits_required:true: use create_credits_checkout.

test

test_mailbox

warmup

warmup_stats

Totals across your mailboxes: today and last 7 days (sent, received, rescued, replied), active and ready counts.

workspaces

list_workspaces

Client 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).

Emailwarmup — questions

Answers built from our own checks of this server.

What can Emailwarmup do?

It exposes 45 tools, read directly from the server on our last check. Among them: add_contacts, add_dns_record, add_hosted_mailboxes, buy_domains, check_dkim, check_dmarc and 39 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Emailwarmup mostly used for?

Its tools cluster around campaign, mailbox and dns. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Emailwarmup working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 12 of 12 checks got a reply (100.0%), average response time 654 ms. The bar chart above shows every period we have measured.

How do I connect Emailwarmup?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Emailwarmup need an API key?

No. Emailwarmup completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 45 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Emailwarmup?

It answers our handshake in 654 ms on average, which is faster than 15% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Emailwarmup open source?

The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at app-emailwarmup.bobwork.ai, which runs on its operator's own terms.
