How to run LinkedIn and email outreach on the same lead list (without two tools)
A practical guide to multichannel outbound: resolving both the LinkedIn profile and the work email for every lead, which channel goes first, how to thread follow-ups, how to stop when they reply, and how to connect Gmail or Microsoft 365 safely.

Multichannel outreach usually means two tools, two lead lists that drift apart, and a prospect who gets a LinkedIn message on Monday and a cold email on Friday from what looks like two different companies. The point of doing both channels is lost when they are not coordinated.
This guide is about doing it properly: one list, one sequence per person, LinkedIn and email in an order that makes sense, and one place where a reply stops everything. It is the process behind the LinkedIn + email play in PumpGTM, written so you can run it by hand first or check that your own tooling does the same.
Why two channels beat one
A cold email from a stranger gets deleted. A LinkedIn connection request from a stranger gets accepted and forgotten. Put them a few days apart and each one makes the other work. The email is now from a face they have seen. The LinkedIn note is now from someone whose email they half remember. Reply rates go up without the copy changing at all.
The catch is that the two touches have to be about the same person, from the same sender, in a sensible order. That is a data problem before it is a writing problem.
Step 1: Resolve both identifiers for every lead
Every row in your list needs two things: a LinkedIn profile URL and a work email address.
Most lists have one or the other. A Sales Navigator export has the profile and no email. A purchased list or a CRM export often has the email and no profile. Fill the gap before you send anything, because a sequence that assumes both will stall on the people missing one.
| You have | How to get the other |
|---|---|
| LinkedIn profile only | Look up the company domain, then a name-at-domain finder for the email. Verify before sending. |
| Email only | Search the name plus company on LinkedIn. Accept only a match with the same current employer. |
| Name and company only | Do both. Drop anyone you cannot match with confidence. |
Expect gaps. In our own data, roughly one lead in six arrives with a usable work email. That is fine. Decide now what happens to people with only a LinkedIn profile (they get the LinkedIn steps and skip the email ones) so nobody gets stuck.
Step 2: Put LinkedIn first
The order matters more than people expect.
- Connection request, day 0. No note. A note reads as a pitch and lowers acceptance.
- Short LinkedIn message, the day after they accept. Who you are, one line on what you do, a small ask.
- Intro email, two days later. This is the message with room for detail: the thing you noticed about their company, the outcome you deliver, two times to talk.
- Email follow-ups on days 4, 5 and 9. Replies in the same thread, one or two sentences each.
Why LinkedIn first: accepting a request costs the prospect nothing, so most people do it. Once they have, the email arrives from a name they recognise and is far more likely to be read. If the request is never accepted, the email still goes out and carries the whole message on its own.
Step 3: Thread the emails and stop on any reply
Two rules make the email side work.
Every follow-up is a reply to the first email. Same subject with "Re:", same thread in their inbox. The prospect can scroll up and see the original. You never have to re-explain yourself, and a follow-up can be one line.
A reply on either channel stops both. If they answer on LinkedIn, no more emails. If they answer by email, no more LinkedIn messages. This is the rule most two-tool setups break, and it is the one that makes you look like a person rather than a system. In PumpGTM the reply detection reads only message headers on your mailbox and freezes that person's sequence the moment something comes back.
Add a one-click unsubscribe to every email and honour it on LinkedIn too. It costs you nothing and keeps your domain out of trouble.
Step 4: Connect your mailbox without handing over your password
You do not need to give any tool your Google password, and you should not.
Google and Microsoft both let you generate an app password: a separate 16-character password for one application, which you can revoke at any time without changing your real one. The steps for Gmail and Google Workspace:
- Turn on 2-Step Verification for the mailbox you want to send from.
- Open the App passwords page in your Google Account and create one named after the tool.
- Paste it into the tool. A well-built tool checks it can both send (SMTP) and read replies (IMAP) before storing anything, and stores it encrypted.
Microsoft 365 and Outlook work the same way through Security info in your Microsoft account. Any other provider works over IMAP and SMTP with its own app password.
Keep the daily send limit per mailbox low, 30 a day is plenty for a founder, and send inside working hours in the prospect's timezone. Deliverability is a reputation you build slowly and lose quickly.
Step 5: Measure both channels on one person
Track four numbers for a fixed window: people contacted, people who accepted the connection, people who replied on any channel, and qualified meetings. Count a person once however many touches they received. If you track email and LinkedIn separately you will double count the same reply and learn nothing.
The question the numbers should answer is whether adding the second channel raised the reply rate for this list. If it did not, the list is the problem, not the channel.
How this runs in PumpGTM
Upload your list or point PumpGTM at a Sales Navigator search. It resolves the LinkedIn profile and the work email for each person. Connect your LinkedIn account and your mailbox on the Accounts page, pick the LinkedIn + Email sequence, edit the message brackets, approve, and press Start. Connection requests go out from your account inside LinkedIn's limits, emails from your own address inside your sending window, follow-ups thread under the first email, and a reply anywhere stops that person and lands in your inbox. People without an email keep their LinkedIn steps and skip the email ones, with a note in the activity log.
The Corgi outbound playbook shows the exact messages one of San Francisco's fastest growing companies sends with this sequence. The multi-touch checklist covers keeping the LinkedIn account itself safe.
Questions founders asked
Can I send the email first? You can. LinkedIn first gets more emails read, because the name is familiar by the time it arrives.
How many emails is too many? Four in total, over about nine days, all in one thread. Then offer a later date and stop.
Do I need a separate sending domain? Not at founder volume. Thirty emails a day from your real address, to people who fit, is normal use.
What if my list has no LinkedIn profiles at all? Run email only, and add the LinkedIn resolution as a second pass. The people who accept the request are the ones to spend your time on.
