Multichannel Outreach: Combining LinkedIn and Cold Email

Multichannel Outreach: Combining LinkedIn and Cold Email cover image

Multichannel outreach means reaching the same lead on more than one channel, usually LinkedIn and email. It works because some people reply on LinkedIn and others on email. A short, personal email after a LinkedIn touch gives you a second chance at a reply without being pushy.

The best outbound teams do not pick LinkedIn or email. They use both. Here is how to do it without doubling your work.

Why multichannel works

Some prospects live in their LinkedIn inbox. Others only check email. A well timed email after a LinkedIn touch, or the other way around, raises your odds of a reply. Both messages need to be personal and match in tone.

A simple multichannel play

  1. Connect on LinkedIn with a personal note.
  2. Once they accept, start your LinkedIn follow-up sequence.
  3. At the same time, send a short, personal cold email that points to the same value. Do not copy your LinkedIn message word for word.
  4. Send any reply, on either channel, to your CRM for fast follow-up.

Writing the cold email

A good cold email has a subject under 60 characters, an opener tied to the lead, one clear ask, and no filler. The body should stand on its own. Assume they never saw your LinkedIn message.

Do it for every lead with AI

On the HeyReplyAI Pro plan, the AI writes a cold email with a subject and body for each lead next to their LinkedIn sequence. Export them as {email_subject} and {email_body} for your email tool, or send replied and hot leads to GoHighLevel for follow-up. One workflow, two channels, all personal.

Write your whole HeyReach sequence with AI

HeyReplyAI writes a personal connection note, every follow-up, and an optional cold email for each lead. Then it sends them into HeyReach as custom variables. Start free with 25 leads.

Frequently asked questions

What is multichannel outreach?

It is reaching the same prospect on more than one channel, most often LinkedIn and cold email. The goal is to meet people where they are most likely to reply.

Should my email copy my LinkedIn message?

No. Keep the same value and tone, but write the email so it stands on its own. Assume the person never saw your LinkedIn message.

What makes a good cold email subject line?

Keep it under 60 characters, make it specific to the lead, and avoid hype. Curiosity beats a sales pitch. See our subject line guide for examples.

Can AI write both the LinkedIn and email copy?

Yes. On the Pro plan HeyReplyAI writes the LinkedIn sequence and a cold email per lead, exported as email_subject and email_body.

Where do replies go?

Route replies from both channels to your CRM, such as GoHighLevel, so you can follow up fast before the lead goes cold.
