Your best membership prospects already gave you their email address. They bought a timed ticket, signed up for a camp, attended an evening event, or made a small gift. They’re sitting in Altru as constituents with no active membership, and most of them will never hear from you again unless someone builds a list and sends something worth opening.
This guide is about turning those records into members by email: who to target, what to send, when to send it, and how to tell whether it worked. Almost all of it relies on Altru data you already collect.
Start with the list, not the email
Acquisition email lives or dies on the segment. A well-written offer sent to everyone in your database will underperform a plain one sent to the right 2,000 people. In Altru, that means building constituent queries rather than exporting a giant ticket-buyer file and sorting it in a spreadsheet.
A solid core acquisition query usually includes:
- Constituents with a ticket or event purchase in a recent window (the last 30, 90, or 365 days, depending on how you plan to use it).
- No current membership, and ideally no membership on anyone in the same household. Emailing a “become a member” offer to the spouse of an active member is one of the fastest ways to look disorganized.
- A valid email address on the record.
- Permission to receive marketing email. Exclude anyone who has opted out or carries a do-not-email or do-not-solicit flag in your setup.
Then layer on the details that change the message. Visit frequency is the big one: someone who bought tickets three times this year is a different prospect from a one-time tourist. Party size matters too, because a family of four paying admission twice has practically already paid for a family membership. Zip code tells you whether a person is local enough for membership to make sense at all.
Lapsed members are a separate segment
Former members who let their membership expire a year or more ago are technically acquisition, but they should not get the same email as first-time visitors. They know your benefits already. Treat them as a “welcome back” audience with their own query and their own message.
Consent deserves a real decision
Buying a ticket gives you a reason to send transactional email: the confirmation, the eTicket, visit details. It doesn’t automatically mean the person agreed to promotional messages. How you handle that depends on your privacy policy, the wording on your checkout and web forms, and the laws that apply to your visitors.
Check what your purchase forms actually say, confirm how that consent is stored on the constituent record, and make sure your acquisition queries filter on it. If you can’t tell from the record whether someone opted in, fix the data capture before you scale up the sending. A smaller list of people who agreed to hear from you will outperform a larger one that generates complaints and unsubscribes.
What to send, and when
Timing matters more than polish. The strongest moment for a membership offer is shortly after a good visit, while the experience is fresh and the admission cost is still on their mind.
- Post-visit thank-you (one to three days after the visit). Keep it short. Thank them, link to something useful (upcoming exhibits, a survey), and include one clear line about membership. Not a hard sell yet.
- The math email (about a week later). Show what membership would have saved on the visit they just made. “Your family’s visit would have been free with a Family membership” is concrete and personal. If you offer to credit a recent admission purchase toward a membership, say so here, and spell out the deadline.
- Benefits and belonging (two to three weeks out). Member events, early access, reciprocal programs, discounts in the shop or café. Pick the two or three benefits your members actually use most, not the full list.
- A deadline nudge. If there’s an admission credit window or a seasonal offer, a final reminder before it closes. Then stop. Prospects who haven’t joined go back into your general newsletter audience.
Before you promise an admission credit, confirm how your staff will apply it in Altru, whether through a discount, a price adjustment, or a manual process at the desk. If you aren’t sure Altru can handle the specific rule you want automatically, test it in a sandbox or ask Blackbaud support before the email goes out. A promise the front desk can’t honor creates more friction than no offer at all.
Keep the path to join short
Every acquisition email should link directly to the membership purchase page, not your homepage. If your online membership form is clunky on a phone, fix that first; many of these emails will be opened on mobile, and a prospect who hits a confusing form rarely comes back to finish.
Measure joins, not opens
Open rates are increasingly unreliable, and clicks only tell you about interest. The number that matters is how many people on each list became members.
- Use source codes or appeals on membership transactions that come from email, so revenue reports can attribute them.
- Use a dedicated promo code or landing link per campaign where your setup allows it.
- Re-run the segment query later. Take the people who received the series and check how many now hold an active membership 30 and 60 days on. Compare that against a similar group who didn’t receive it if you can hold one back.
Some people will join at the desk on their next visit rather than clicking the email. The re-query approach catches those conversions; click tracking alone misses them.
Clean data before you send
Ticketing tends to create duplicate constituents: the same visitor buying online with one email and in person with another. Duplicates mean the same person gets your series twice, or a current member gets an acquisition offer because their membership sits on a different record. Running a duplicate review on your recent ticket-buyer records before launching a campaign is worth the time.
Where Social Good can help
The segmentation, consent, and measurement work above is Altru work, and none of it requires additional tools. The part that often stalls is the sending: exporting query results every week and rebuilding emails by hand. Email Designer sends automated, branded emails directly from Altru queries, so a post-visit membership series can go out on schedule without manual exports.
Quick answers
How soon after a visit should the first membership email go out?
Within a few days. The value of membership is easiest to see while the admission cost is recent.
Should we email every ticket buyer?
No. Filter out current members and their households, people without marketing consent, and, for most offers, visitors from far outside your area.
How many emails in an acquisition series?
Three or four over roughly a month is a reasonable starting point. Watch unsubscribes and adjust.
