Multichannel outreach

Multichannel outreach is contacting the same prospect on more than one channel, usually email and LinkedIn and sometimes the phone, in one planned sequence where each touch follows from the last and a reply on any channel stops the rest.

What counts as multichannel outreach

You write to one person on two or more channels, and the channels know about each other. The email on day three can mention the connection request you sent on Monday. The LinkedIn message after an accepted invitation can pick up where the email left off. And a reply anywhere ends the follow-ups everywhere. A cold email campaign and a separate LinkedIn campaign sent to the same list are two single-channel campaigns, and the person on the other end can tell.

In B2B the usual channels are:

  • Email to a verified work address. It carries detail and a link, and it comes with rules of its own (below).
  • LinkedIn: a profile visit, a connection request with or without a note, then messages once you are connected. The person sees your face and your work history before they read a word.
  • Phone, often kept for people who already engaged on another channel.

How a multichannel sequence works

  1. One list, checked once. Each person needs a verified email and a LinkedIn profile that belong to the same human, so the two channels never reach two different people under one name.
  2. Steps in order, with waits and branches. A connection request first, an email a few days later, a LinkedIn message only once the invitation is accepted, and a different next step for each outcome.
  3. One stop rule. A reply on either channel pauses every remaining step on both.
  4. One inbox. Replies from both channels land in one place, so whoever answers sees the whole conversation.

The rules a sequence has to meet

Every channel's rules apply at once. For email, Gmail has required since February 2024 that anyone sending more than 5,000 messages a day to Gmail addresses set up SPF, DKIM and DMARC, keep the spam rate reported in Postmaster Tools below 0.3% and give marketing mail a one-click unsubscribe. Every sender, whatever the volume, needs SPF or DKIM, valid forward and reverse DNS, a TLS connection and the same spam rate ceiling.1

An objection covers every channel. The UK regulator calls the right to stop your data being used for direct marketing absolute, with no exemptions, so a request to stop that arrives by email has to end the LinkedIn steps too.2

In GetSales, when a person answers on either channel, every workflow they are in pauses for them by default. A reply the AI SDR labels Do not contact puts the person on your stoplist in Co-pilot and Auto-pilot alike, a step no team can switch off. And every reply from every sender profile lands in one inbox.

Marketing qualified lead (MQL)

A marketing qualified lead (MQL) is a lead that marketing has judged ready for sales, because the person fits your customer profile and has done enough, such as opening the pricing page or asking for a demo, to be worth a call. Sales then decides whether it becomes a sales qualified lead.

Outbound sales

Outbound sales is selling by reaching out first: the seller chooses the companies and people to contact and opens the conversation by email, LinkedIn or phone before the buyer has asked to hear from anyone.

LinkedIn InMail

LinkedIn InMail is a paid message you can send to a LinkedIn member you are not connected to. Sellers use it to reach buyers outside their network and recruiters to reach candidates, without waiting for a connection request to be accepted.
