If your organisation sends regular mailings, such as renewal letters, statements or patient letters, I can almost guarantee the printing isn't the part that gives you a headache. It's everything around it.
Finding last month's files. Re-explaining the instructions. Checking the right insert goes in the right envelope. Chasing someone for the data. Quietly hoping nothing has changed since the last run.
I've spent over 25 years in print and mail. A job that happens every month should get easier every month. Very often it doesn't, and it's rarely anyone's fault. The job was simply never set up to repeat. This guide explains how to set up regular mailings so they run the same way every time.
Key points
- Regular mailings go wrong in the admin around the print, not the print itself.
- A written recurring mailing specification removes most of the monthly back-and-forth.
- Every regular mailing needs three fixed dates: data, approval and mailing.
- One supplier for data, print, enclosing and postage means fewer hand-offs and fewer errors.
What are regular mailings?
Regular mailings are letters an organisation sends on a repeating schedule as part of running the business. They are sometimes called recurring mailings or transactional mail. Unlike a one-off marketing campaign, the format, data and timing stay largely the same from run to run.
Common examples include:
- Renewal notices and payment reminders
- Account statements and annual summaries
- Patient, appointment and recall letters
- Membership updates and policy or plan documents
- Tenant and resident letters for housing providers
Because these letters often carry personal information and a deadline, accuracy and timing matter more than design.
Signs your regular mailing starts from scratch every month
If two or three of these ring a bell, your process is costing you time it doesn't need to.
- The same questions come up every run: which envelope, which insert, which class of post.
- One person "just knows" how the job works, and nobody else could run it tomorrow.
- The data file arrives in a slightly different layout each time.
- Artwork gets re-sent and re-checked from scratch, even when nothing has changed.
- You're coordinating more than one supplier for print, enclosing and postage.
- Deadlines are agreed by email, job by job, rather than set once.
None of these is a disaster on its own. Together, every single month, they add up.
Why regular mailings drift back to square one
Most regular mailings start life as a one-off. Someone sets the job up, it goes out, and next month it gets repeated by copying whatever happened last time.
The trouble is, the details end up living in a trail of emails and in people's heads. A new insert gets added. Someone goes on holiday. The CRM is updated and the data export changes. The job still goes out, but it's running on memory and goodwill rather than a process.
For letters that carry real value, like renewals, statements and patient letters, "it usually works" isn't good enough.
What to include in a recurring mailing specification
When a new regular job comes to us, the first thing we do is write it down properly. Not a quote. A specification.
It sounds dull, I know. But it saves more back-and-forth than anything else, because it holds everything that should stay the same between runs. From then on, each month you only need to confirm what has changed. A good specification covers:
- Schedule: how often the job runs and the target mailing date for each cycle.
- Data format: the exact fields, column names and file type.
- Print specification: paper, size, colour, single or double sided, and any personalisation.
- Inserts and enclosing: what goes in each pack, in what order, and any rules for different groups.
- Envelopes: size, window position, who supplies them and how much stock to hold.
- Postage: service and class, and who approves the cost before each run.
- Approvals: who signs off proofs and counts, and who covers when they're away.
- Exceptions: what happens with late files, split batches or extra inserts.
My quick test: could someone who has never touched the job run it tomorrow using only the specification? If not, that gap is exactly where your monthly effort is going.
The three dates every regular mailing needs
So much last-minute pressure comes from dates that were never properly agreed. Work backwards from when the letters need to land, and fix these three for every cycle.
- Data deadline. When the final data file must be with your mailing house. In my experience, late data is the most common reason a regular job slips.
- Approval deadline. When proofs and counts must be signed off. Name the person who approves it, and their backup.
- Mailing date. When the letters are handed over for delivery. Agree it once and repeat it every run.
Once these are set, nobody has to ask "when do you need it by?" again.
Running regular mailings in-house or with a mailing house
Plenty of organisations start by printing and posting regular letters themselves. That works at low volumes. As volumes and frequency grow, the hidden cost is usually staff time rather than paper and ink.
| In-house | With a mailing house | |
|---|---|---|
| Staff time | Printing, folding, enclosing and franking each run | Your team sends the data and approves the proof |
| Postage | Usually standard business rates | Access to sorted and barcoded postage options where volumes qualify |
| Data security | Depends on your own processes | Agreed handling, ideally with ISO 27001 certification |
| Cover | Relies on whoever usually does it | A team and a written process behind every run |
If your team spends hours on a mailing every month, it's worth comparing the full cost, not just the print price.
Why one supplier for data, print, enclosing and postage helps
When one company prints, another encloses and someone else handles postage, your team becomes the glue in the middle. Every hand-off is a chance for a file to be the wrong version or a date to be misunderstood.
We're a family-run business, and we've always kept it simple: regular mailing services with data handling, print, enclosing and postage under one roof, with one team you can actually speak to. When something changes, you only need to say it once.
It matters for the data too. Regular mailings usually carry personal information, so you should know exactly where your files go and who handles them. We're ICO registered and certified to ISO 27001 for information security and ISO 9001 for quality, and we agree how data is sent, stored and deleted before the first run. If you're a housing provider, our guide to direct mail for housing associations covers this in more detail.
A five-minute check for your regular mailing
Before your next run goes out, answer these honestly.
- Is there a written specification for this job, or does it live in someone's head?
- Does your data arrive in the same format every time?
- Are your data, approval and mailing dates fixed for every cycle?
- How many suppliers touch this mailing before it reaches the post?
- If your usual contact was off tomorrow, would the job still go out?
If you answered "no" or "not sure" to more than one, your monthly mailing is probably starting from scratch more often than it needs to.
Regular mailings: frequently asked questions
What are regular mailings?
Regular mailings are letters an organisation sends on a repeating schedule as part of running the business, such as renewal notices, account statements, payment reminders, patient letters and membership updates. They are also called recurring mailings or transactional mail.
What is a recurring mailing specification?
One document that sets out how a regular mailing runs: the schedule, data format, print specification, inserts, envelopes, postage, approvals and what to do with exceptions. It gives everyone the same reference point so the job doesn't rely on memory.
Do we still need to check each run if we have a specification?
Yes. A specification doesn't remove the need for checks, but it makes them quicker. Instead of re-checking everything, you confirm what has changed, such as quantities, data and any new inserts.
Is it worth outsourcing regular mailings we already run in-house?
It depends on volume, frequency and how much staff time the job takes. If your team spends hours each month printing, folding, enclosing and franking, or the job relies on one person, it's worth comparing the full cost, not just the print price.
How is customer data kept secure in a regular mailing?
Choose a mailing house that is ICO registered and certified to ISO 27001, the international standard for information security, and agree in writing how data is sent, stored and deleted. Mailings Direct holds both and sets this out as part of every regular job.
If any of this sounds like your regular mailing, tell me what you send and how often. We'll talk through the specification and schedule with you before we quote, so the service fits the job.
