Email Deliverability for Recruiting & Staffing

What email deliverability means for Recruiting & Staffing

Must integrate with Bullhorn, Jobvite, or Greenhouse ATS for candidate lifecycle triggers. Two-sided audience segmentation (employer vs. candidate) with separate campaign logic. EEOC-compliant targeting parameter guardrails. Talent community re-engagement automation.

For Recruiting & Staffing teams the relevant marketing pains are: Two-sided market problem: firm must run simultaneous marketing programs for employers (B2B sale) and candidates (B2C recruitment) with entirely different messages, channels, and KPIs; Candidate pipeline goes stale quickly — most CRMs don't have the workflow logic to re-engage placed candidates at the right moment (12–18 months post-placement); LinkedIn Recruiter and LinkedIn Marketing Solutions are separate products with separate data — impossible to attribute employer brand spend to actual placements; EEOC and employment law restrictions mean job ad copy and targeting parameters must avoid demographic inference (no age, gender, or race targeting); ATS (applicant tracking system) data is the richest candidate intelligence available but rarely integrates with marketing automation; Contingency vs. retained search firms have fundamentally different go-to-market motions that require different campaign architectures; Employer brand content (culture, DEI, benefits) requires deep client collaboration and long production cycles that don't fit standard content calendars. EEOC equal employment opportunity advertising rules (no discriminatory targeting), OFCCP requirements for federal contractor clients, CAN-SPAM, TCPA (SMS to candidates), LinkedIn ad policy, state employment agency licensing disclosure requirements, GDPR for EU candidate data

The Technical Foundation: Authentication and Reputation

Three DNS-based standards form the technical floor of deliverability. SPF (Sender Policy Framework) specifies which mail servers are authorized to send on your domain's behalf. DKIM (DomainKeys Identified Mail) cryptographically signs each message so receiving servers can verify it wasn't tampered with in transit. DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do when SPF or DKIM fails — quarantine, reject, or monitor — and sends aggregate reports back to the sender.

Beyond authentication, sending reputation accumulates over time at the IP and domain level. Mailbox providers like Google, Microsoft, and Yahoo use engagement signals — open rate, click rate, reply rate, spam complaints, and unsubscribes — to score each sender. A spam complaint rate above 0.10% is enough to trigger filtering at Gmail. New sending domains must warm up gradually: starting at a few hundred emails per day and doubling weekly over 4–6 weeks before reaching full volume.
