Diagnostic centres · WhatsApp marketing
Send the report link and the fasting reminder, not a flood of package offers.
WhatsApp marketing for a diagnostic centre covers booking confirmations, preparation instructions, report delivery and the occasional check-up offer, all from one business number. Reports are health data, so consent and who can see the chat matter more here than in most trades. GullySales sets up the number, the templates and the consent record.
A 90-minute audit call and a written, scored report. Turnaround, reporting and term are agreed in writing after the audit.
What WhatsApp marketing means
WhatsApp marketing is sending updates, offers and reminders to customers on the app most Indian buyers already check daily, which gets read faster than email or SMS. GullySales sets up business WhatsApp, writes the message templates and keeps the list consented and current.

For diagnostic centres
Where it usually goes wrong, and what we would do.
“Reports sent from a technician's own phone”
When a technician forwards a scan report from her personal WhatsApp, the centre loses the record and the patient's data leaves the building at six. Every report should go from the business number.
“The wrong report reaches the wrong number”
One digit typed wrongly at billing sends a stranger someone's biopsy result. Read the number back at registration, and check the name and date of birth before a report goes out.
“Offers sent to people who only wanted a report”
A number given to receive a report is not permission for package offers. Ask separately for that, and record the answer.
What we do
What we deliver for diagnostic centres.
Every deliverable, what it covers for you, and the result it is there to produce. Nothing here is an extra.
One business number for every department
Pathology, imaging and the health-check desk answering from one WhatsApp Business account, with chats assigned to the right desk.
Result: The patient deals with one centre, not three phones.
Preparation messages for each test
Templates for fasting, a full bladder before a pelvic scan, what to bring to an MRI and which medicines to ask the doctor about.
Result: Fewer patients arrive unprepared and have to rebook.
Report delivery with an identity check
A routine for sending reports as a link or PDF, with the patient's name and date of birth checked first.
Result: The report reaches only the patient it belongs to.
Consent for offers kept apart from consent for reports
Two ticks at registration, one for reports and reminders and one for check-up offers, stored against the patient record.
Result: Offers go only to people who agreed to them.
An away message with collection hours
A reply for late messages giving collection timings, and a line telling anyone with an emergency to go to a hospital.
Result: A message sent at midnight gets a useful answer.
Package catalogue for the check-up desk
Check-up packages in the WhatsApp catalogue with the tests in each and the preparation, kept in step with the website.
Result: A family can compare packages inside the chat.
How the result is measured
- Messages delivered
- Reply rate
- Enquiries from WhatsApp
Recorded as a baseline before work starts, so every later report has an honest comparison.
What must be in place first
Settle these before a diagnostic centre sends reports or offers on WhatsApp.
- Two separate opt-ins at registration
- One tick for reports and reminders, another for check-up offers. Record both against the patient, and read the number back aloud so a typo never sends a report to a stranger.
- A verified business profile for the centre
- Use the registered name, address, collection hours and website. Decide whether branches share one account or run their own before staff start using personal phones.
- Approved templates for reminders and reports
- Fasting reminders, report-ready messages and recalls that you start may need approved templates and may be charged per conversation. Check WhatsApp's current business policy and pricing before the first template is drafted.
- Who pays and who may broadcast
- Decide which department's budget carries the messaging charges and who may send an offer. Three desks sending offers to the same patient turn into blocks and complaints.
- An opt-out that works
- Honour a stop request at once and mark it on the record. Keep sending the reports the patient is owed, and nothing else.
- A person behind the chat
- Name the desk that answers report questions and the senior person who handles a patient upset by a result. A bot may confirm a slot but must never interpret a report.
Who it is for
This is written for these diagnostic centres.
- Standalone diagnostic centres with pathology and imaging
- Diagnostic centres inside or beside a hospital
- Multi-branch diagnostic chains
- Diagnostic centres that run corporate camps
- Centres with a strong health check-up business
- Centres serving senior citizens and families
Not for
It is not the right fit if.
- You want a guaranteed Google ranking or a guaranteed number of leads. Nobody honest can promise either.
- You need enquiries by next week and have nobody to answer them.
- You want posts and reach reported, not enquiries and orders.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Free audit call
90 minutes with whoever handles your enquiries: how they arrive, how fast they are answered, where they are lost.
After the call
Written, scored report
Six areas scored, fixes ranked by return and cost. If you want our help, the scope, the fee and the reporting come with it, in writing.
Before work starts
Baseline recorded
Enquiries by source, reply time, conversion and cost per order, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
Usually the cheapest one on the report: reply time, a follow-up sequence or the marketing-to-sales handover.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
How the work runs for diagnostic centres
- 1
Listen to how a patient moves between departments
The free audit call traces where enquiries come from, who answers them and what a single-test caller hears about everything else.
- 2
Join the departments at the front door
One enquiry route, one sheet and a log that shows which package or test was asked about.
- 3
Make the packages findable
A page for each package, a Business Profile that shows the range and reviews asked for after a smooth visit.
- 4
Reach clinics and corporates with one offer
A sheet for referrers and a single proposal for corporates.
- 5
Report on packages, not activity
A report on enquiries, packages sold and returning patients, against the baseline taken before anything changed.
Proof
What happened when owners fixed this.

Why us
Why owners pick GullySales over an agency.
Marketing and sales, as one job

No account managers in between. You are never handed to someone you have not met.
A baseline before anything starts
Your numbers are written down on day one, so every later report compares against something honest.
The fee in writing, split three ways
Our time, your media spend and production on separate lines. You always see what goes to us.
No guarantees we cannot keep
The term is agreed in writing and never a default twelve months. We never promise a ranking or a lead count, because nobody controls those.
