Plenty of people only ever do one thing. Send postcards. Or send invoices. Never both, even when both would genuinely help the business behind them.
Take a professional services firm. Its finance team sends client invoices and statutory notices through the platform's virtual printing, triggered automatically from its accounting system via the direct mail API. It runs every month, on autopilot, and has done for years. Nobody in business development realises Stannp.com could just as easily send a well-timed letter to past clients. A note to former conveyancing clients as the property market picks up, for instance. Half the platform going unused.
Stannp.com does two different jobs from one account: marketing mail (postcards, personalised campaigns) and transactional mail (invoices, statements, notices).
Most accounts only ever use one side, even when the business has a real use case for both.
Mail is a trusted channel for both jobs: 71% of consumers say they have complete trust in the mail they receive, according to Royal Mail.
Marketing mail is anything sent to persuade someone to do something: a postcard with an offer, a personalised letter inviting someone back. Transactional mail is anything sent because something already happened: an invoice, a statement, a booking confirmation, a renewal notice.
Stannp.com handles both from one account. Marketing mail leans on campaign creation, personalisation and design tools, along with tracking like QR codes, and integrations that trigger mail from your CRM or marketing platform. Transactional mail can run through virtual printing or the bulk mailer. You can send it automatically from events in your own systems via the direct mail API, or by uploading a PDF, or a data file and template, through the platform. Either way, there's no design work each time once the format's set.
Both sides benefit from the same thing: a channel people actually engage with. Mail interaction rates hit a five-year high in Q2 2025, with 9.2% of direct mail prompting a visit to an advertiser's website, according to DMA and JICMAIL data. And on our own platform data, Stannp.com has sent over 200 million items, so the tooling behind both sides is well proven.
Usually because whoever set the account up had one specific job to do, and solved exactly that. A finance team needs invoices sent automatically, so they set up virtual printing and move on. A marketing team needs a postcard campaign, so they set up templates and personalisation and move on. Neither team necessarily knows the other is using Stannp.com at all. And neither has had a reason to ask whether it could handle the other kind of mail too.
It's a bigger gap in the businesses least likely to have one team overseeing both: a one-person operation juggling everything themselves might genuinely not have had time to explore beyond the one feature they signed up for, while a larger business with a dedicated design team on one side and finance on the other might have simply never connected the two.
Back to the professional services example. The finance team's virtual printing setup already proves the platform works. Notices go out reliably, on schedule, with no manual intervention. That same reliability is exactly what a business development team would want for a very different kind of mail: a personalised reminder to lapsed clients, an invitation to a client event, a thank-you note after a case closes.
Neither team needs to touch the other's setup. Marketing mail and transactional mail can sit side by side in one account, so adding one doesn't disrupt the other. Some customers already work this way, sending transactional mail through the API and running bulk marketing campaigns through the platform, all from one account. And because everything runs through one account, your plan's benefits apply to all of it. The business gets more value out of something it's already paying for, without adding a second supplier to manage.
One thing to check: Free and Starter plans include one user, so if different teams need their own logins, compare plans on our detailed pricing page.
For marketing mail:
Personalisation at no extra cost. Variable data, including names, offers and images, costs the same as sending identical mail.
QR codes, so you can track who actually engages with a campaign.
ProspectFeed, for finding newly registered businesses to target.
Campaign scheduling and templates, so recurring sends don't need rebuilding from scratch each time.
The direct mail API and webhooks, so sends trigger automatically from events in your own systems.
Upload routes, so you can send a PDF, or a data file and template, straight through the platform with no developer involved.
Virtual printing, built specifically for statements, notices and confirmations rather than one-off campaigns.
Address verification, catching errors before they become undeliverable mail.
Next working day dispatch on active subscription plans, so time-sensitive notices don't sit in a queue.
If you're set up for one and curious about the other, it's worth ten minutes in the dashboard rather than a new sign-up. The features sit inside the same account you already have.
For marketing mail, that means checking the campaign and design tools. For transactional mail, you have two routes: upload a PDF, or a data file and template, through the platform, or connect the API if you'd rather trigger sends from your own systems. The API and integrations both need a paid plan (you can compare them on our detailed pricing page). The API route usually needs a developer, while integrations connect through your CRM or marketing platform.
Either way, there's no minimum order, so it's easy to test whether the other side is worth setting up properly.
If you're already sending with Stannp.com, log in and have a look through the dashboard for whichever side you haven't set up. If you're new, create your free account, and you can send both kinds of mail from day one, with no minimum order and no need to decide up front which one you'll actually use.
Marketing mail persuades someone to act: a postcard with an offer or a personalised campaign letter. Transactional mail confirms something that's already happened: an invoice, a statement, a booking confirmation, or a renewal notice.
Yes. Both run from the same account. Marketing mail leans on the campaign and design tools, while transactional mail can run through virtual printing or the bulk mailer, with the API as an option. Setting one up doesn't affect the other. In our experience, most customers who send both use a single account, which means your plan's benefits apply to everything they send. Free and Starter plans include one user, so if different teams need their own logins, compare plans on our detailed pricing page.
Anything triggered by an event that's already occurred: invoices, statements, appointment confirmations, renewal notices, and similar automated correspondence. It's typically sent via virtual printing rather than built as a one-off campaign.
No. Stannp.com charges the same whether a piece is personalised or identical, on both marketing and transactional mail. There's no separate pricing tier for variable data.
No. It works at any size. A one-person business sending a handful of invoices a month can use it on any plan, and higher volumes simply need a plan with more virtual printer items, which you can compare on our detailed pricing page. It works the other way too: a small business can test a marketing postcard without hiring a designer, because there's no minimum order.
No. You can upload a PDF, or a data file and template, through the platform. The API is there if you want sends triggered automatically from your own systems, and that route usually needs a developer or whoever manages your tech stack.
Yes. Stannp.com integrates with CRM and marketing platforms such as HubSpot and Salesforce, and with Zapier and Make for the rest of your stack, so an event like a customer going quiet can trigger a postcard automatically. The direct mail API is there if you'd rather build something custom. Both the integrations and the API need a live API key, which comes with a paid plan.
Transactional mail is triggered via the direct mail API or a CRM/marketing platform integration, based on events in your own systems. It usually needs a developer or whoever manages your existing tech stack to make the connection, and both the API and integrations need a paid plan.
