Getting Started with Squibb

Section 1

What Squibb Is (and What It Is Not)

Squibb is a cold email platform with the sending infrastructure built in. You bring an audience (or let Squibb find one), approve the emails, and it sends them for you.

Traditional cold email is a technical project before it is a sales project. You buy extra domains, create inboxes, configure DNS records, wait weeks for the inboxes to warm up, and then monitor deliverability so your emails do not land in spam. Squibb removes that whole layer: emails go out through Squibb’s own sending domains, which Squibb sets up, warms, and maintains. You can be sending the same day you sign up.

The workflow in three steps

What Squibb is not

• Not a guarantee of customers. Squibb gets your emails out; your targeting and your offer decide whether anyone replies. Squibb’s own terms make no promises about inbox placement, replies, or sales.
• Not for consumers. It is built for business-to-business outreach. Purchased consumer lists are banned.
• Not hands-off legally. Emails go out in your name, and you are responsible for what they say and who receives them (Section 3).
• Not LinkedIn or calendar automation. Squibb is focused on email. Booking meetings happens in your own replies and calendar tool.

Section 2

Plans, Credits, and the Free Trial

Squibb runs on credits. Understanding the credit math up front is the difference between a month of steady outreach and an account that pauses in week one.

All plans include Squibb’s sending infrastructure, AI sequence writing, CSV uploads, lead-source integrations, reporting, and the Squibb Inbox. Prices were current in October 2026; check Squibb’s pricing for today’s offers.

How credits are spent

Rules worth knowing

• Free trial: Starter starts with 30 free days and its full credit allowance. A card is required, and $30 is charged when the trial ends unless you cancel first. Squibb Leads becomes available once the plan is paid (or immediately on Growth and Pro).
• Plan credits expire one month after they are granted; unused ones do not roll over. Purchased top-up credits do not expire but are non-refundable.
• Running out pauses, it does not overcharge. A campaign that runs out of credits holds its place and resumes when your balance covers the next email.
• Auto top-up is optional. If you turn it on, set a daily or monthly spend cap.
• Your current balance and plan show in the top right corner of the app at all times.

Section 3

Before You Send: The Legal and Practical Basics

Cold email to businesses is legal in the United States when you follow a few clear rules. Squibb handles some of them automatically; the rest are on you.

What Squibb does for you

• Adds a working unsubscribe link to every email and processes opt-outs automatically.
• Inserts your physical mailing address into your emails (you must provide a real one in your account).
• Keeps accurate sender and header information, and stops a sequence the moment someone replies or unsubscribes.
• Verifies addresses and maintains a suppression list so opted-out people are not contacted again.

What you are responsible for

• You are the sender. Emails go out in your name, so every claim must be true and the subject line must not mislead.
• Business purposes only. Contact people in their professional role about something relevant to their work.
• Lawful lists only. Never upload purchased or scraped consumer lists, or people who have opted out from you.
• Know the rules where you send. Squibb’s terms name CAN-SPAM (US), GDPR and UK GDPR/PECR (Europe and UK), and CASL (Canada). Europe and Canada are stricter than the US about unsolicited email.
• No prohibited offers, including adult content, weapons, unlicensed gambling, MLM, and unregistered securities.

Have these ready

• A clear audience: industry, job title, company size, and location (for example, owners of residential contracting companies in California with 5 to 50 employees).
• A specific offer: what you do, for whom, and the result. One sentence.
• A simple next step you want prospects to take: reply, book a call, or visit a page.
• A landing page or website if you plan to drive traffic.
• Your business mailing address for the account settings.

Section 4

A Tour of the App

Squibb’s interface is clean and simple. Everything lives in the left sidebar, with your credit balance always visible at the top right.

The Home screen also shows locked cards for Target audiences, Offers, and Agent Mode, and the sidebar promotes Agent Mode. These belong to the optional $15/month Agent Mode add-on (Section 10). You do not need it to run campaigns.

Section 5

Finding and Managing Leads

Your results depend more on who you email than on anything else. The Leads page is where you build and check that audience.

Three ways to add leads

Reading the Leads table

• Email status: Verified addresses are safe to send to. Undeliverable ones are skipped; do not try to work around this, because bounces damage deliverability.
• Engagement: filter by Not contacted, No response, Clicked, Replied, Bounced, or Unsubscribed. These filters become your follow-up lists later.
• Score: Squibb’s rating of how well a lead matches. Higher is better.
• Lists and Segments: lists are where leads came from; segments are saved filters that campaigns pull from. Use New segment to group, for example, all verified owners in one state.
• Download CSV exports your leads at any time.

Section 6

Creating and Launching a Campaign

A campaign bundles three things: who you email, what you send, and how it is scheduled. Every campaign carries its own leads, sequence, and settings.

Building the campaign

Click New campaign in the sidebar or Create Campaign on the Campaigns page. The builder walks you through a few short steps. The exact screens evolve, but you will make these decisions:

1. Choose an objective. Replies campaigns aim for conversations; Traffic campaigns send prospects to your website, landing page, or product link and track clicks.
2. Pick your audience: a list or segment from the Leads page.
3. Create the sequence: write the emails yourself, or have Jett or Sable draft them from a short brief about your business, audience, and offer. A typical sequence is 3 steps: a first email and two follow-ups a few days apart.
4. Review every email. Read each step as if you were the recipient. Fix anything inaccurate, generic, or pushy (Section 7 has a checklist).
5. Check settings and launch. Until you launch, the campaign stays a Draft.

Campaign statuses and controls

The Campaigns table shows each campaign’s objective, status, number of leads, number of steps, results, and last activity. Use the three-dot menu on a row for more actions.

Section 7

Writing Emails That Get Replies

The AI agents write a decent first draft. Your edits are what make it sound like a person worth answering.

The rules of good cold email

• Short. 50 to 120 words. If it does not fit on a phone screen, cut it.
• About them, not you. Lead with a problem they have, not your company history.
• One ask. A single, low-effort next step: “Worth a quick chat?” beats a calendar link and three questions.
• Specific proof. One concrete result or example beats a list of adjectives.
• Plain and honest subject lines. No fake “Re:” or “Fwd:”, no clickbait. Misleading subjects are illegal under CAN-SPAM and wreck trust.
• Follow-ups add something. Each follow-up should offer a new angle, example, or question, not “just bumping this.”

Example 3-step sequence

For a bookkeeping firm emailing residential contractors:

Section 8

Handling Replies in the Inbox

Replies are the whole point. Squibb collects them so nothing gets lost, and stops the sequence for anyone who answers.

• Squibb Inbox: every reply lands here, grouped by campaign. You can read, reply, and ask Squibb to draft a response, which you approve before it is sent.
• Forwarding inboxes: have replies forwarded to your normal email (2 addresses on Starter, 5 on Growth, 10 on Pro).
• Connected mailboxes (Growth and Pro): connect a Gmail or Outlook account to receive replies and send your answers from it. Connected mailboxes never send the campaign emails themselves.

Not every reply is a yes. Answer polite “not now” replies politely, and treat “remove me” as an unsubscribe. Squibb stops the sequence automatically either way.

Section 9

Domains and Deliverability

By default, your emails go out through Squibb-managed sending domains. That is what makes same-day sending possible.

Squibb handles the technical setup, warm-up, and reputation of its sending domains. Because this infrastructure is shared with other customers, Squibb watches every account’s bounce and complaint rates closely.

If you want emails sent from a domain that is yours, the Domains page lets you buy one through Squibb. Squibb registers it, manages the DNS and mailboxes, and starts sending campaign email from it once the mailboxes have warmed up. Expect a waiting period before a new domain is ready.

Keep your deliverability healthy

• Send only to verified addresses, and never re-import bounced or unsubscribed contacts.
• Keep targeting tight. Irrelevant emails get marked as spam, and complaints hurt everyone on shared infrastructure.
• Avoid spam triggers: all-caps, excessive links, attachments, and hype words like “guaranteed” or “free money.”
• Watch the Bounced and Unsubscribed filters on the Leads page. A rising rate means your list or message needs work.

Section 10

Agent Mode (Optional Add-On)

Agent Mode is Squibb’s autopilot for improving a running campaign. It costs $15/month and is switched on per campaign.

When you switch it on, you authorize Squibb to write and send new versions without approving each email. That makes the credit limit the most important setting: start low, review the versions it writes every few days, and raise the limit only when you like what you see. You can pause it or switch it off at any time; the campaign keeps sending the sequences it already has.

Section 11

Running Squibb from Claude (MCP)

Squibb’s official MCP connector lets you manage leads, campaigns, and replies by chatting with Claude in plain English. No API key, nothing to install.

MCP (Model Context Protocol) is an open standard that lets an AI assistant use outside tools. Squibb’s connector works in the Claude app, on claude.ai, and on mobile, on Claude’s Free, Pro, Max, Team, and Enterprise plans. The same link also works in ChatGPT, Perplexity, and Le Chat.

Set it up in Claude (about a minute)

1. In Claude, go to Settings > Connectors and click Add custom connector.
2. Name it Squibb and paste this URL, then click Add:
   https://app.squibb.ai/api/mcp Copy
3. Click Connect. A Squibb sign-in window opens; approve access and it closes on its own.
4. In a chat, click the + button, choose Connectors, and switch Squibb on.
5. Test it: “Squibb, how many leads do I have?”

You need an active Squibb workspace first. Already a customer? The MCP page inside the app at app.squibb.ai/mcp has the same link.

Things you can ask for

Section 12

Measuring and Improving Results

Judge a campaign after at least 100 to 200 people have received the full sequence; smaller numbers are mostly noise. Then look at three numbers.

What to change, in order

1. Audience first. If nobody replies, the wrong people are probably getting the email.
2. Offer second. Make the result more specific or the next step easier.
3. Copy third. Test a new first line or subject line.

Change one thing at a time so you know what worked, or let Agent Mode run the tests for you.

Common Mistakes to Avoid

Most disappointing first campaigns trip over the same few things.
