Why it matters

Every great hire starts with a message that arrives

You can automate the perfect recruiting sequence and still lose the candidate if it never reaches the inbox. Deliverability is the difference between outreach that opens conversations and outreach that quietly vanishes into spam. Here is how to keep your candidate emails delivered, opened, and compliant - built into ATS Mako, not bolted on.

Five levers

What actually drives inbox placement

Deliverability is not luck. It is five controllable levers, and ATS Mako handles the technical ones so recruiters can focus on the conversation.

01

Authenticate Your Sending Domain

Inbox providers trust senders they can verify. SPF, DKIM, and DMARC records tell Gmail, Outlook, and Yahoo that email from your domain is really from you - not a spoofer. Without them, recruiting emails land in spam or get bounced outright. ATS Mako sends from your own branded domain when you white-label your instance, so your candidate emails carry your reputation, your logo, and your authentication - not a shared vendor address. Your brand, codified, all the way down to the SMTP handshake.

02

Warm Up and Protect Sender Reputation

A brand-new domain that suddenly blasts 10,000 candidate emails looks exactly like spam to a mailbox provider. Reputation is earned through consistent volume, low complaint rates, and real engagement. ATS Mako sequences send at a measured pace and route through infrastructure built for high inbox placement, so your outreach ramps the way providers expect. The result: your first-touch messages actually reach the candidate instead of a filtered folder they never open.

03

Keep Lists Clean and Engaged

Bounces, dead addresses, and disengaged recipients drag your sender score down and pull good emails into spam with the bad. ATS Mako captures verified applicant emails at the source through your branded Apply Here page, tracks opens, clicks, and replies in real time, and lets you segment dynamic audiences by engagement. You send to people who want to hear from you - and your deliverability climbs because of it.

04

Honor CAN-SPAM Unsubscribes Automatically

US email law requires a clear, working unsubscribe link and prompt removal of anyone who opts out. Miss it and you risk penalties and a wrecked reputation. ATS Mako handles unsubscribe processing automatically: the opt-out link is built into every sequence, requests are honored in real time, and the recipient is suppressed from all future campaigns. Your lockable template sections keep the required physical address and opt-out language in place - recruiters cannot accidentally strip them.

05

Write Sequences Candidates Open

Deliverability is not only technical - content matters. Spam-trigger phrases, all-caps subject lines, and image-only emails get filtered. Personalization and relevance get opened. ATS Mako sequences use dynamic merge fields like {{first_name}}, {{position}}, and {{interview_time}} so every message reads one-to-one, plus conditional logic that auto-follows-up only when there is no reply. Fewer generic blasts, more real conversations - and a sender reputation that keeps improving.

Risky vs. reliable

Where deliverability breaks - and how to fix it

The same six factors decide whether your recruiting email lands. Here is the difference between a setup that gets filtered and one that gets read.

Factor

Domain authentication

Risky

Emails send from a shared vendor domain or an unauthenticated address. No SPF, DKIM, or DMARC alignment, so providers treat every message as suspect.

The ATS Mako way

White-labeled sending from your own authenticated domain. SPF, DKIM, and DMARC aligned so mailbox providers verify and trust every send.

Factor

Sender reputation

Risky

A cold domain fires a 10,000-email blast in one shot. Volume spikes, complaints rise, and the whole domain gets throttled or blocklisted.

The ATS Mako way

Measured send pacing on infrastructure tuned for high inbox placement. Reputation ramps the way providers expect, keeping placement steady at volume.

Factor

List hygiene

Risky

Imported spreadsheets full of stale, unverified, or guessed addresses. Hard bounces pile up and drag every future send toward spam.

The ATS Mako way

Verified applicant emails captured at the source via your branded Apply Here page. Engagement tracked and audiences segmented so you send to live, interested candidates.

Factor

Unsubscribe handling

Risky

A recruiter manually removes opt-outs from a list - sometimes days later. Someone gets emailed after asking to stop, and CAN-SPAM exposure follows.

The ATS Mako way

Unsubscribe link in every sequence, opt-outs honored in real time, and the recipient suppressed from all future campaigns automatically. No manual step to forget.

Factor

Message content

Risky

Generic, all-caps, image-heavy blasts with spam-trigger phrases. Low opens, high complaints, and filters that learn to route you to junk.

The ATS Mako way

Personalized sequences with merge fields and conditional follow-up. Relevant, one-to-one messages that get opened - which lifts placement over time.

Factor

Engagement visibility

Risky

No idea who opened, clicked, or replied. You keep emailing people who will never respond, quietly eroding your sender score.

The ATS Mako way

Real-time open, click, and reply tracking on a timestamped activity feed. Prune the disengaged and double down on the candidates who signal interest.

The delivery loop

From authenticated send to honored opt-out

One connected loop keeps your candidate email fast, deliverable, and compliant - from first touch to offer letter.

  1. 01

    Authenticate

    Send from your own trusted domain

    White-label your ATS Mako instance so recruiting emails ship from your branded domain with SPF, DKIM, and DMARC aligned. Candidates see your name in the from line, and mailbox providers verify you on the first hop.

  2. 02

    Capture

    Collect verified emails at the source

    Your branded Apply Here page turns every submission into an applicant record with a verified email address instantly. No manual imports, no guessed addresses, no spreadsheet rot dragging down your reputation.

  3. 03

    Sequence

    Personalized outreach at a healthy pace

    Multi-step sequences send with merge fields and conditional logic on infrastructure built for high inbox placement. Follow-ups fire only when there is no reply, so you stay relevant instead of noisy.

  4. 04

    Track

    Watch engagement in real time

    Opens, clicks, and replies land on a timestamped activity feed the moment they happen. Segment dynamic audiences by engagement and keep sending only to candidates who are paying attention.

  5. 05

    Suppress

    Honor every unsubscribe automatically

    The CAN-SPAM opt-out link lives in every sequence and lockable template. When a candidate unsubscribes, ATS Mako removes them in real time and suppresses them from all future campaigns - no recruiter action needed.

Recruiting email deliverability FAQ

What is email deliverability in recruiting?

Email deliverability is the measure of how many of your recruiting emails actually reach the candidate inbox instead of the spam folder or a hard bounce. It depends on technical factors like domain authentication (SPF, DKIM, DMARC) and sender reputation, plus behavioral factors like list quality, engagement rates, and how relevant your content is. Strong deliverability means your first-touch messages get seen, your sequences get opened, and your pipeline keeps moving from first touch to offer letter.

Why do recruiting emails end up in spam?

The most common causes are an unauthenticated or shared sending domain, a cold domain sending high volume too fast, stale or purchased lists that generate bounces and complaints, spam-trigger language and image-only layouts, and a missing or broken unsubscribe link. Each of these signals to mailbox providers that you may be a low-quality sender. ATS Mako addresses them together: branded authenticated sending, measured pacing on high-placement infrastructure, verified emails captured at the source, personalized sequences, and automatic unsubscribe handling.

How does ATS Mako help with CAN-SPAM compliance?

CAN-SPAM requires a clear, working unsubscribe mechanism, prompt removal of anyone who opts out, and a valid physical postal address in commercial email. ATS Mako builds the unsubscribe link into every sequence, honors opt-outs in real time, and suppresses the recipient from all future campaigns automatically. Lockable template sections keep the required legal language and physical address in place so individual recruiters cannot accidentally strip them. This guide is general information, not legal advice - confirm your specific obligations with counsel.

Do I need my own domain to get good deliverability?

Sending from your own authenticated domain is one of the strongest levers you have. When you white-label ATS Mako, recruiting emails ship from your branded domain with SPF, DKIM, and DMARC aligned, so your candidate outreach builds your reputation rather than sharing a pool with unrelated senders. Your logo, your colors, your domain - reinforced on every message from first touch to offer letter.

How do email sequences improve inbox placement?

Placement improves when candidates engage. ATS Mako sequences use dynamic merge fields and conditional logic to send personalized, relevant messages that get opened and replied to instead of ignored or reported. Real-time open, click, and reply tracking lets you segment out the disengaged and focus on interested candidates. Higher engagement plus lower complaints teaches mailbox providers to trust you, which lifts placement for every future send.

Can I track whether candidates actually open my emails?

Yes. ATS Mako logs opens, link clicks, and replies in real time on a timestamped activity feed tied to each candidate profile, with instant recruiter alerts. You can see exactly who is engaging, follow up while interest is hot, and prune addresses that never respond - which protects your sender reputation and keeps deliverability strong.
