How to Measure Whether Follow Up Messages Are Moving Scans to Interviews

Published Nov 5, 2026

Laboratory workers in white coats discuss a sheet of paper in a bright laboratory, with colleagues, microscopes, samples, and equipment behind them.

You can connect QR scan data from direct mail to interview outcomes with a simple spreadsheet workflow that avoids complex CRM setups. This guide is for hospital and health-system talent teams who already mail licensed professionals and need a clear view of whether later messages move scans into interviews.

Give the first postcard and every later message its own landing page, short URL, and QR code.
Log each visit in a shared spreadsheet with date, source, and contact details.
Add interview invitation, completion, and offer status next to the original scan.
Compare what share of scans from each message reach interviews, then adjust timing or copy.

RecruitCard runs managed, end-to-end direct mail recruiting campaigns with targeting by license type, specialty, and geography, plus QR code and landing-page response tracking. The workflow below uses that scan trail without claiming any specific response rate or time to mailbox.

1. Create separate landing pages for the initial mail piece and each follow up message

Separate pages let you see which physical piece produced each visit instead of mixing every scan into one bucket.

Assign a unique short URL and QR code to the original postcard

Print one QR code and one short URL on the first card. That pair should open only the page written for the first contact. Keep the recipient first name, a specialty-specific message, employer branding, and one clear action on that card.

Create distinct landing pages for every follow up message sent after the first contact

Each later card, letter, or reminder needs its own page. Do not reuse the first URL. If you mail a second or third piece, give it a new QR code so a scan can never be miscounted as the original drop.

Ask for basic contact details and how they heard about the role

Each page should collect a name, a way to reach the person, and a short note on which mail piece they used. That note is a backup if a scan arrives without a clean source tag.

If you want this tracking built into a full-service mail campaign (targeting, creative, print, postage, delivery, and QR tracking), book a 15-minute call.

2. Record every scan and visit in a shared spreadsheet

A shared sheet is enough to keep scan sources visible without waiting on a CRM rebuild.

Log date, source URL or QR code, and contact information

Create one row per visit. Capture the calendar date, which URL or QR produced the visit, and any name or contact fields the person submitted.

Add columns for follow up message number and scan date

Label the first mail piece as message 1. Label later pieces as message 2, message 3, and so on. Keep the scan date in its own column so you can sort by when interest showed up.

Update the sheet whenever a new scan or visit is detected

When your tracking tool shows a new hit, add the row the same day if you can. Stale logs make it harder to match a scan to an interview later.

3. Track interview stage outcomes alongside the scan records

Interview data belongs on the same row as the scan so you can see the path from mailbox to conversation.

Add columns for invitation date, interview completion, and offer status

Use plain values such as invited, completed, declined, or offer. Do not invent conversion percentages here. You only need dates and stage names.

Enter outcome data manually as candidates move through hiring

When talent acquisition sends an interview invite, type the date on that row. When the interview happens or an offer is decided, update the same row. Manual entry is slower than automation, but it keeps the source of the scan intact.

Keep entries tied to the original scan source

Never split a person into a new row just because they reached interview. The conversion path stays visible only if the QR source, the message number, and the interview stage sit together.

4. Compare conversion rates across message versions

Side by side rates show which follow up actually moved people from a scan to an interview.

Calculate the share of scans from each source that reach interview

For each message number, divide interview completions (or invitations, if that is your chosen stage) by the number of scans from that source. Write the result as a percentage you computed from your own sheet. Do not import a published industry rate.

Review the numbers side by side

Look at message 1 versus later pieces. A later card that produces fewer scans but a higher share of interviews may still be the stronger mover. A first card that produces many scans but almost no interviews may need a clearer call to action or a better landing page.

Use the results to adjust future timing or content

If a second message lifts interview share, keep that specialty-specific copy and test when you send it. If a version does not move people past the scan, change the message or the page, not the license, specialty, and geography targeting itself.
