Why email-only outreach underperforms
Email is still the workhorse. It carries the full pitch, it's cheap to send, and nobody rations how many they receive. But building an entire desk on it has three structural problems.
Reachability. A real slice of any candidate list has no findable work email, a dead personal address, or an inbox they check twice a month. On an email-only desk, every one of those people is unreachable by definition, before quality even enters the conversation.
Attention. The people you most want are the people every other recruiter and every SDR is also emailing. In a crowded inbox your carefully written message sits next to 40 that look exactly like it. The same person's LinkedIn inbox or phone is dramatically quieter.
Channel preference is real. Some people live on LinkedIn and treat email as an archive. Some answer texts and nothing else. A passive candidate who was never replying to your email might still accept a connection request from a recruiter with a relevant role. That gesture costs them nothing.
The recruiter's channel stack
Four channels matter on an agency desk, and each has a distinct job.
Email: the full pitch
The only channel with room for the complete story. Why them, why the role, comp, location, process. Best first touch when you have a verified address, and the natural home for the detailed follow-up.
LinkedIn: presence and credibility
The connection request is the lowest-friction touch in recruiting. There's no message to ignore, and acceptance is permission to talk. The DM that follows sits in a quieter inbox than email, next to a profile that proves you're a real recruiter with a real role. InMail covers the people you can't connect with. And for candidates it's the channel of least surprise, because being recruited is what LinkedIn is for.
SMS: speed at the decision point
Texts get read almost immediately. That makes SMS the wrong channel for a cold pitch and the perfect one for momentum. Confirming interest, nudging a scheduled call, reaching the candidate who went quiet the day before an interview. Short, late in the sequence, always with an obvious way out.
Phone: where deals actually close
Nobody accepts an offer over email. The call is where qualification, negotiation, and commitment happen. The earlier channels exist to earn the call, and a phone task should appear automatically the moment the signals say someone's warm.
One sequence, not four campaigns
The mistake most desks make when they go multichannel is running the channels in parallel silos. An email tool, a LinkedIn routine, a call list, each with its own state. That's how a candidate gets a follow-up email the day after they replied on LinkedIn, which reads worse than any single-channel campaign ever could.
Multichannel only works as one sequence with one memory. That means branching logic. No verified email found? The sequence falls back to InMail instead of skipping the person. Connection accepted? The DM fires. And the non-negotiable rule: a reply, a booking, or an opt-out on any channel stops every channel at once.
Run that way, the channels compound instead of stacking. The connection request makes the email familiar ("the recruiter from LinkedIn"), the email makes the DM specific, and by the time a phone task surfaces, the person has seen your name three times in two quiet places.
Email, LinkedIn connection requests, DMs and InMails, SMS, and phone tasks in one branching campaign, with replies from every channel in one inbox.

My default for candidate outreach, adjustable by seniority and market:
- Day 1: LinkedIn connection request. No note, or one short line naming the role. The profile visit does the introducing.
- Day 2: Email. The full pitch in three short paragraphs. Why them, the two or three details that make the role worth a look, one question.
- Day 4: LinkedIn DM (or InMail if the connection is pending). A different, shorter angle than the email. One new fact, one question.
- Day 7: Email follow-up. New information only. Comp confirmed, the hiring manager's background, interview process. Never "just floating this to the top."
- Day 10: Phone task. For anyone who showed a signal. Opened twice, viewed your profile, accepted the connection. Signals mean the call is warm.
- Day 12: Final email. Close the loop, keep the door open, file them for the next relevant role.
For BD the same skeleton holds with the channels shifted a step later. Hiring managers guard their inboxes harder, so the LinkedIn touches carry more of the load early. Either way, the sequence stops everywhere the moment anyone replies.
What the numbers should show
Measure multichannel at the person level, not the message level. What percentage of people contacted replied on any channel? That's the number email-only desks can never see, because their unreachable segment never enters the denominator.
And watch where replies actually arrive. It's common for a third or more to come back on a different channel than the touch that triggered them. The email gets read, the answer shows up as a LinkedIn message two days later. That pattern is invisible without a single inbox across channels, and it's the clearest proof the channels are working together instead of just coexisting.
