Warming up
Recruiters live in two channels at once: email to candidates and clients, and LinkedIn to everyone. When the mailbox spam-folders or the LinkedIn account gets throttled, the pipeline stops — and you usually find out a week too late.
A recruiter's job is volume outreach to people who never asked to hear from them. That is the exact profile that mailbox providers and LinkedIn watch most closely. You are sending dozens of near-identical messages a day to candidates and hiring managers, and the systems on the other side are tuned to treat that pattern as risk. Get the reputation layer wrong and your best-written InMail or follow-up never gets seen.
Most outreach advice assumes a single channel. Recruiters don't have that luxury. A typical desk runs candidate sourcing and client business development side by side, and both depend on outreach landing. Email carries the long-form pitch, the role spec, and the follow-up thread. LinkedIn carries the first touch, the connection request, the InMail, and the quiet relationship-building that turns a passive candidate into an applicant.
The problem is that both channels punish the exact behavior recruiting requires. Email providers flag accounts that suddenly send 40 cold messages a day from a mailbox with no sending history. LinkedIn restricts accounts that fire off connection requests faster than a real person would, or that get ignored too often. A recruiter ramping a new desk is, from the platform's point of view, indistinguishable from a spammer — unless the account has earned a reputation first.
Warmerly covers both layers. It warms your Gmail or Microsoft 365 mailbox so candidate and client email reaches the inbox, and it warms and paces your LinkedIn activity so your account stays inside the limits that keep it unrestricted. One tool, two channels, the same goal: the message gets seen by a human.
Candidate outreach is cold email by every technical definition. You found someone on LinkedIn or a job board, you have their work address or a guessed pattern, and you're emailing them about a role they didn't apply for. Gmail and Outlook score that mail on sender reputation: has this mailbox sent real, engaged-with email before, or did it appear one Tuesday and immediately start blasting?
A brand-new recruiter mailbox, or a fresh agency domain, has no reputation to draw on. The first batch of candidate emails is the riskiest mail you will ever send from that address. If even a handful bounce on guessed addresses or get marked as spam by uninterested candidates, the mailbox's score drops and the next batch lands in spam at a higher rate. The decline compounds quietly until someone notices reply rates have collapsed.
Warmup fixes the starting position. Before you send a single candidate email, Warmerly runs real peer-to-peer traffic through the mailbox: messages that get opened, replied to, and pulled out of spam. That activity tells Gmail and Microsoft the mailbox belongs to a real person who sends real mail. By the time your sourcing campaign starts, the account has a reputation that can absorb the normal friction of cold outreach instead of cratering on day one.
Client business development email has the same exposure with higher stakes. A spam-foldered candidate is a missed placement. A spam-foldered pitch to a hiring manager you've been chasing for a quarter is lost revenue. Both run from the same mailbox, so both rise and fall with the same reputation score — which is why warming it is not optional for a desk that bills on outreach.
LinkedIn is the recruiter's primary channel, and it has its own reputation system that most people never see until they hit a wall. The platform doesn't publish exact thresholds, but it watches connection-request volume, acceptance rate, message frequency, and how human your activity pattern looks. Cross an invisible line and your account gets restricted: requests stop going out, search gets capped, or the account gets a warning that scares you off the platform entirely.
Recruiters hit these limits faster than almost anyone because the job demands high outreach volume. A new account that immediately sends the maximum allowed connection requests, with messages that read as templated, gets a low acceptance rate — and low acceptance rate is one of the strongest signals LinkedIn uses to throttle an account. The fix is not to send less forever. It's to ramp like a real professional would and keep activity inside safe, account-specific limits.
Warmerly paces LinkedIn activity so your account builds standing instead of tripping alarms. New accounts ramp gradually rather than starting at full volume. Connection requests and messages go out on a human-looking schedule, not in machine-gun bursts. The account stays inside conservative daily limits that protect it from restriction. The aim is a LinkedIn presence that can run candidate and client outreach for years without getting flagged — not a burst of activity that gets the account limited in week two.
Because recruiting works across channels, Warmerly treats email and LinkedIn as one reputation problem with two surfaces. A candidate you connect with on LinkedIn often gets a follow-up by email, and a hiring manager you email often gets a LinkedIn touch first. Both need to land. Warming one and ignoring the other leaves half your pipeline exposed.
The mechanics are the same whether you're a solo recruiter or a 30-seat agency. The discipline is what changes results.
Warmerly is the reputation layer, not a replacement for your ATS, sequencer, or LinkedIn automation. It connects to your Gmail or Microsoft 365 mailbox via standard OAuth — the same method your sequencing tool uses — and runs warmup traffic in the background. It connects to your LinkedIn account to pace and warm activity. Then it surfaces health and limit data in one dashboard so you can see, at a glance, whether your outreach foundation is sound before you scale sending.
That separation keeps it compatible with the tools recruiters already run. Use Warmerly alongside your sequencer, your ATS, your CRM, and your LinkedIn outreach tool. It doesn't touch your candidate lists, your sequences, or your placements — it makes sure the mailbox and the LinkedIn account underneath them are in good standing so those messages actually arrive.
Warmerly is priced flat, not per mailbox or per seat. Whether you run one mailbox or warm every recruiter's account on an agency floor, the price doesn't change as you add people. For desks that onboard recruiters regularly, that predictability is the point.
These come up on nearly every recruiting desk that starts paying attention to deliverability and LinkedIn health.
Every feature below is available on every plan, including the starting tier.
Email warmup keeps candidate and client mail in the inbox. LinkedIn warmup and pacing keep your account inside safe limits. Recruiting runs on both surfaces, so Warmerly protects both from the same dashboard.
New accounts ramp gradually and activity stays inside conservative daily limits, so connection requests and InMail keep going out instead of getting your account restricted at the worst possible moment.
Warmerly checks SPF, DKIM, DMARC, and MTA-STS every day for every connected mailbox. If a record breaks, you get a remediation note before candidate and client email starts spam-foldering.
Seed tests run across Gmail, Outlook.com, Microsoft 365, and other providers. Candidates skew Gmail, enterprise hiring managers skew Microsoft 365 — you see placement on both before it costs you a placement.
Add every recruiter's mailbox and LinkedIn account for one flat monthly price. Onboarding a new hire doesn't raise your warmup bill, so the cost stays predictable as the desk grows.
Connect a mailbox in 60 seconds. Warmerly starts monitoring immediately and begins the warmup sequence automatically.
Yes. Warmerly runs email warmup for your Gmail or Microsoft 365 mailbox and warms and paces your LinkedIn activity. Recruiters work across both channels, so both are covered from one account. You can connect either or both.
The opposite — the goal is to keep it unrestricted. Warmerly ramps new accounts gradually and keeps activity inside conservative, human-looking limits so connection requests and messages keep going out. Restriction usually comes from sending too much too fast with low acceptance rates, which paced warmup is designed to avoid.
Yes. Warmerly is the reputation layer, not a sequencer or automation platform. It connects to your mailbox via standard OAuth and runs in parallel with your sequencer, ATS, CRM, and LinkedIn outreach tool. It doesn't touch your candidate lists or campaigns.
For a new mailbox on an established domain, two to three weeks of warmup is typically enough before careful cold sending. For a brand-new agency domain under 60 days old, allow three to four weeks. Starting too early is the most common cause of a desk's email landing in spam.
Warmerly is priced at a flat monthly rate — not per mailbox and not per seat. You can warm every recruiter's mailbox and LinkedIn account for the same price as warming one. Check the pricing page for current plan details.
Agencies don't run one mailbox. They run ten, fifty, or a hundred — across client domains, managed at scale. The economics of warmup look completely different when you're responsible for all of them.
SDRs and AEs depend on cold email delivering to the inbox. One domain deliverability problem doesn't stay isolated — it can affect the reply rates of everyone on the team sending from the same domain.
