How to Use Postcards Before a Trade Show: A Week-by-Week Plan

To use postcards before a trade show, choose the companies you most want to meet at the event, mail a personal invitation to the right people at each one six to eight weeks before the show, and give them a specific reason and an easy way to book time with you, such as a reserved demo slot linked to a unique QR code. Follow up by email and phone in the weeks before the show, and send a thank-you card after it.

Most exhibitors rely on whoever walks past the booth. Pre-show mail lets you decide who you meet. This guide is part of our broader guide to generating leads with postcards.

Who to mail before a trade show

If the organizer provides an attendee list, check the rules on how you may use it before mailing. To build a list of attendees and exhibitors yourself, see sending postcards to companies attending an upcoming trade show and how to build a targeted mailing list.

Choose one goal for the card

A pre-show card can ask for different things. Pick one per segment:

• Pre-booked meeting: the strongest goal for high-value accounts. A reserved 20-minute slot at the booth or a quiet meeting room.
• Booth visit: fine for a broader list, but give a concrete reason to stop by, such as a live demo at set times.
• Private event: a breakfast, dinner or small briefing for senior people who won't queue at a booth. See mailing invitations to a private dinner during a conference.

What to put on a pre-show postcard

• The recipient's name and company.
• The show name, dates and your booth number.
• One reason to meet you, tied to their situation.
• A unique QR code that opens a booking page with open time slots.
• The name of the person they'll meet, who also signs the card.

For setup details, see postcards with individual QR codes linking to a trade show booking page.

Example invitations

These examples use made-up companies and a made-up show.

Hi Priya, you'll be at Packaging Expo in Toronto on March 4 to 6. I've set aside a few 20-minute slots at booth 412 to show how Northfield's line changeovers could run faster. Scan to pick one. — Marco

Hi Daniel, we're both exhibiting at Fleet Ops Canada next month. If you'd like to compare notes on routing for regional fleets, coffee is on us at booth 218. Scan to book a time.

Hi Sandra, we're hosting a small breakfast for operations leaders on day two of the conference, a short walk from the venue. Eight seats, no slides. Scan to request a place.

Week-by-week campaign timeline

Postal delivery times vary, so work backwards from the show with a buffer. With Yotru, mailing usually starts two to three days after an order is finalized, and delivery usually takes about a week, sometimes two to three weeks.

At the show: make the mail visible to booth staff

Give everyone working the booth a short list of booked meetings, mailed accounts and who scanned. When someone from a mailed company stops by, staff can say "You may have received our card" and pick up the conversation. Record which visitors came from the mailing so you can measure it afterwards.

After the show: follow up while it's fresh

Inboxes fill up after a trade show, and many exhibitor follow-up emails look the same. A personal thank-you card referring to your conversation stands out. Send it within a week or two. For contacts who went quiet after the show, a second card with a new angle can restart the conversation; see personalized thank-you postcards for trade show contacts and postcards for trade show leads who haven't replied.

Meetings booked at the show are only valuable if someone follows them up properly; how to book more B2B sales meetings with direct mail covers the sequence after the first conversation.

How to measure a pre-show campaign

• Meetings booked before the show from mailed accounts.
• Meetings actually held at the show.
• Booth visits from mailed accounts that didn't book in advance.
• Opportunities and revenue from those conversations over the following months.

Compare cost per meeting from the mailing with your overall cost per booth conversation. Because a booth is a large fixed cost, even a modest number of extra pre-booked meetings can change the return on the whole event. How to track leads and sales from postcards explains the setup, and postcard campaign costs shows the budget math.

Common mistakes

• Mailing too late. Cards that arrive in show week can't fill a calendar that's already full.
• "Visit us at booth 412" and nothing else. Every exhibitor says this. Give a reason and a booking link.
• Mailing everyone on the attendee list. Focus on accounts you'd actually prioritize at the booth.
• Booth staff who don't know about the mailing. They miss the chance to connect the visit to the card.
• No post-show plan. Leads cool quickly once everyone is back at their desks.

How Yotru helps

Yotru can build a list of target accounts and decision-makers for your show, or work from your own list. Each invitation is personalized, signed by the person they'll meet, and carries a unique QR code that links to your booking page. You get an alert when someone scans, and you approve the recipients before you pay. See mailing invitations to book demos at your trade show booth.

Frequently asked questions

When should I send postcards before a trade show?

Six to eight weeks before the show is a safe target. That allows for printing and delivery, and leaves time for people to book meetings and for you to follow up.

Who should I send pre-show postcards to?

Target accounts likely to attend, relevant exhibitors, companies near the venue, open opportunities and key customers, addressed to named decision-makers.

What should a trade show invitation postcard say?

The recipient's name, the show and your booth number, one specific reason to meet, a booking link or QR code, and the name of the person they'll meet.

How do I get trade show attendees to visit my booth?

Invite chosen attendees before the show with a personal reason to stop by and a way to reserve time, then remind them by email or phone in the final weeks.

Can I get a list of trade show attendees to mail?

Some organizers share attendee lists with exhibitors under specific rules. Otherwise, build a list from past attendees, speakers, exhibitors and companies matching the show's audience.

Should I send postcards after a trade show too?

Yes. A personal thank-you card within a week or two of the show stands out from the flood of follow-up emails and helps turn conversations into meetings.

How do I measure a pre-show direct mail campaign?

Count meetings booked and held from mailed accounts, booth visits from mailed accounts, and the opportunities and revenue that followed.
