How to Reactivate Past Applicants for New Openings With ATS Mako

Why start with people who already applied

Every opening tempts you to post a new ad and wait. But your applicant database already holds people who raised their hand. Some were runners-up. Some applied to a location that closed its role. Some were a good fit at the wrong time. Knowing how to reactivate past applicants for new openings turns that database into a working shortlist. It is the core of candidate rediscovery, and it works best when your past applicants live in one searchable system instead of old inboxes and spreadsheets.

With ATS Mako, the job breaks into three stages. Segment the right people. Message them through SMS and email under your own brand. Track who responds and move them straight into screening and interviews. The sections below walk through each stage, then cover what to measure and the mistakes that slow teams down.

Stage 1: Segment past applicants for the new role

Reactivation fails when you blast everyone. It works when the message matches the person. Before you write a word, decide who belongs on the list for this specific opening.

1. 1 Define the opening clearly Write down the role, the location, the shift pattern and the must-have requirements. This becomes your filter for everything that follows. For multi-location teams, be specific about which site is hiring.
2. 2 Search your applicant database Use Global Search to find past applicants by the terms that matter for this role, such as job title, skills or location. Pull up people who applied to similar roles, not just the identical one.
3. 3 Review prior outcomes Open each record in applicant management and check how far they got last time and why the process ended. Strong finalists and people who withdrew for timing reasons are your first wave.
4. 4 Rank against the new opening Use AI candidate ranking to sort the shortlist against the new role's requirements. Ranking helps you decide who to contact first. A recruiter or hiring manager still makes the call.

Who to include and who to leave out

• Include: finalists who were not selected, applicants who matched a role at another location, and people who withdrew because of timing or schedule.
• Include: candidates who completed screening and showed the skills the new role needs.
• Leave out: anyone who asked not to be contacted, or who opted out of messages.
• Leave out: applicants who were not a fit for reasons that still apply to this role.
• Split the list into small groups by location or role so each message can be specific.

Stage 2: Message past applicants by SMS and email

Past applicants did not ask to hear from you today. Your first message has to be short, personal and easy to answer. ATS Mako includes native SMS and an integrated email client, so you can reach people on the channel they use most without leaving the platform. Because the system is a white-label applicant tracking system, the experience carries your company's brand, which helps people recognize who is contacting them.

Lead with SMS for hourly and high-volume roles

For shift work and frontline roles, a text is often the quickest way to get a reply. Keep it to a few lines. Name the role, the location and one clear next step.

Hi [First name], this is [Recruiter name] from [Company]. You applied with us for [previous role] a while back. We now have a [new role] opening at [location], [shift/schedule]. Interested? Reply YES and I'll send next steps. Reply STOP to opt out.

Use email for detail and salaried roles

Email gives you room to explain pay range, responsibilities and why you thought of this person. Use it as the main channel for professional roles, or as a follow-up to a text.

Subject: A new [role] opening at [Company]

Hi [First name],

You applied for [previous role] with us, and we were impressed with your background. A [new role] position has opened at [location], and your experience in [relevant skill] lines up well with what the team needs.

Here is a quick summary:
- Role: [new role]
- Location: [location]
- Schedule: [schedule]

Stage 3: Track responses and move people forward

Sending messages is the easy part. The value comes from acting on replies fast. Real-time engagement tracking shows you how past applicants are engaging as it happens, so recruiters can focus on the people who respond instead of guessing.

1. 1 Watch for replies and engagement Check engagement on your reactivation messages throughout the day. Prioritize anyone who replied or showed interest.
2. 2 Screen interested candidates Send interested applicants to AI voice screening to confirm availability, interest and basic requirements without booking a recruiter call for every person.
3. 3 Book interviews quickly Use interview scheduling to let candidates pick a time that works for them and the hiring manager. A short gap between reply and interview keeps momentum.
4. 4 Update every record Move each candidate to the right stage in applicant management. Note who declined, who asked to be contacted later, and who did not respond, so the next campaign starts with clean data.
5. 5 Onboard the hire When you make an offer, move the new hire into onboarding, including digital W-4 and new-hire tax forms, so paperwork does not delay the start date.

Follow up once, then pause

If someone does not reply, one polite follow-up on a different channel is reasonable. A text followed by an email, or the reverse. After that, mark the record and leave them for a future opening. Repeated messages damage your brand with people you may want to hire later.

Outcomes to measure

Track a small set of numbers for each reactivation campaign. Compare them to roles filled through new postings. Results will vary by role, location and how recent your past applicants are, so judge the approach on your own data.

Common pitfalls

• Messaging the whole database. Broad blasts feel impersonal and lead to opt-outs. Segment by role and location first.
• Ignoring why someone left the process. Read the record before you reach out. A candidate who was rejected for a missing requirement should not get the same message as a finalist.
• Slow follow-up. A reply that sits for days often goes cold. Assign someone to watch engagement during each campaign.
• Generic copy. Name the role, the location and the reason you thought of them.
• Skipping record updates. If declines and no-replies are not logged, the next campaign repeats the same mistakes.
• Treating reactivation as a one-off. Keep capturing new applicants through your apply pages so the database stays fresh for the next opening.
