When we started working with the Open Property Data Association (OPDA), its newsletter went out the way many association newsletters still do: as a PDF attached to an email, with every member CC’d on the same message.
It’s an easy habit to fall into. The PDF looks polished, it can be printed for the board, and everyone already has an email account. But it quietly costs you members’ attention, and it tells you nothing about what’s working.
This article covers what a PDF newsletter really costs, what we changed for OPDA, and a practical plan you can follow to make the switch yourself.
Why so many associations do it
Membership organisations tend to have small teams with big remits. The person writing the newsletter is often also running events, answering member queries and preparing papers for the board. A PDF feels like the safe choice:
- it looks like a “proper” publication
- it can be designed once and sent as-is
- it doesn’t need another piece of software or another login
- it’s how it has always been done
None of those reasons is wrong. But each one trades a little convenience now for a lot of lost engagement later.
What a PDF newsletter costs you
You can’t see who’s reading. No opens, no clicks, no idea which stories landed. You can’t tell your board what members care about, because you don’t know.
It’s hard to read on a phone. Most people check email on mobile, where a PDF means downloading, pinching, zooming and, usually, giving up.
It’s hard to find later. Attachments get buried in inboxes. Content published on your website keeps working for years: it can be found in search, shared by members and linked to from future emails.
CC lists are a data risk. Every recipient can see every other member’s email address. Under UK GDPR, that’s a personal data breach waiting to happen, and one “reply all” away from embarrassment.
One size fits nobody. Everyone gets the same message, whether they’re a new contact, a long-standing member or a board director. There’s no way to send the right content to the right people.
It can’t grow with you. You can’t automate a welcome email, a renewal reminder or an event follow-up from a PDF.
What we changed for OPDA
OPDA is the UK’s independent, not-for-profit industry body for smart property data, with members including major banks, building societies, estate agents, conveyancers and proptech firms. Its members are busy, senior people, so every email has to earn its place.
We didn’t start with anything fancy. We started with the basics.
1. Proper email campaigns
We moved OPDA onto an email platform, so each member receives their own copy of every email. No more CC lists, no more exposed addresses, and every send is tracked.
2. Content that lives on the website
Instead of attaching a PDF, each newsletter now links to articles, news and resources on OPDA’s website. The email is short and scannable; the detail lives on the site, where it can be found in search, shared and read on any device.
3. A regular rhythm
We set a bi-weekly schedule for member content. Consistency matters more than volume: members learn when to expect you, and your team can plan ahead instead of scrambling.
4. A welcome journey
New contacts now hear from OPDA straight away, with a short sequence explaining who OPDA is, what it’s working on and how to get involved. Welcome emails are the most-opened emails most organisations send, and they were previously missing entirely.
5. Tagging and segmentation
We connected the website’s forms to email tagging rules, so every enquiry reaches the right place and members get content relevant to them. A bank doesn’t necessarily want the same updates as a conveyancer.
6. Campaigns for key moments
With the foundations in place, we ran campaigns for the moments that matter: the membership drive, AGM feedback, and the launch of OPDA’s annual research report, The Future of Homebuying, which we also copy-edited and designed.
What happened
In the last year, OPDA sent 245% more emails across 29 campaigns, and people opened them:
- 37% open rate, with opens up 233% year on year
- Email clicks up 187%, with 514 clicks through to OPDA content
- The website’s busiest month on record when the research report launched, with around 2,500 sessions
None of this needed a big budget or a new CRM. It needed a clear plan and someone to set it up properly.
How to make the switch yourself
If your newsletter is still a PDF, here’s the order we’d tackle it in.
Week one: stop the CC. Move your mailing list into an email platform (Mailchimp, HubSpot and many CRMs include one). Import only the contacts you have permission to email, and send your next newsletter from there, even if it’s still mostly a link to the PDF.
Week two: move the content online. Publish your next newsletter’s stories as posts on your website and link to them from a short email. Keep the email to a headline, a sentence and a link for each story.
Week three: add a welcome email. Write one short email for new contacts: who you are, what you do for members and one thing they can do next. Switch it on and forget about it.
Month two: start tagging. Add a simple tag for each member type or interest, and use your sign-up and enquiry forms to set it. You don’t need twenty segments. Three or four is plenty to start.
Month three: look at the numbers. Which stories got the most clicks? Which subject lines got opened? Use what you learn to plan the next quarter’s content, and share it with your board.
A few things to avoid
- Don’t just send the PDF from a new platform. You’ll fix the CC problem, but you’ll still have no idea what anyone reads.
- Don’t write a wall of text. The email is a signpost, not the destination.
- Don’t send “because it’s Friday”. Every email should have a reason to exist.
- Don’t forget accessibility. Real text, not images of text, with clear headings and descriptive links, so everyone can read it.
If you’d like help making the switch, we’ve done it for membership organisations of every size, and email marketing is a big part of what we do.
