Most speakers mean to post about your event and never do. That's the whole problem - and it's fixable, because speakers are your highest-leverage advocates: they have the exact audience you want, and a post from them reads as a personal endorsement, not an ad. Speaker-shared posters drive up to 40% more event registrations - a directional planning figure from events run on Premagic (the advocacy engine explains how to read those). Your job is to remove every excuse between "I should share this" and "posted."
Your 20 speakers share the campaign
Activate your speaker roster and each one posts a personalized 'I'm speaking' card to their own followers - a warm referral that converts far better than any ad. Watch it cascade into registrations, then compound.
The moment they confirm
Removing every excuse starts with timing. Don't wait. The second a speaker is confirmed, hand them a personalized "I'm speaking at…" asset - their face, name, and session, ready to post in one tap. Excitement is highest at confirmation; capture it.
A weekly run-up cadence (T-10 to event day)
One asset isn't a campaign. Hand speakers fresh, personalized content every week, from announcement to event day, so their feed never feels repetitive - each week a different angle:
- T-10 - The reveal: "I'm speaking at {event}" announcement card.
- T-9 - Why it matters: the problem their session solves, or why the topic is timely right now.
- T-8 - Session teaser: the one takeaway attendees walk away with.
- T-7 - Who should attend: the roles and peers who'd benefit - tag a few of them.
- T-6 - A hot take: a bold or contrarian opinion pulled straight from their talk.
- T-5 - Behind the scenes: prepping the talk, a slide sneak peek, or a quick demo clip.
- T-4 - Social proof: a past-talk clip or testimonial, or simply why they're excited.
- T-3 - Ask the audience: "what do you want me to cover?" - a poll or open question.
- T-2 - Agenda highlight: other sessions or speakers they're looking forward to (cross-promotes the event).
- T-1 - Countdown: "See you tomorrow at {event}."
- Event day - Live: an "I'm on stage now" story plus a photo from the room.
Mix the formats too - a text post, an image or poster, a short video, a carousel, a poll - so the algorithm keeps resurfacing it and their network sees the event many times, not once.
Post it everywhere, not just LinkedIn
That weekly cadence only pays off if it travels. LinkedIn is the workhorse for B2B, but a speaker's reach multiplies when the same moment goes out across every channel they own. Generate each asset pre-sized for all of them so "post it" never means "go design five versions":
- LinkedIn - the primary B2B channel; post it and pin it to their "Featured."
- X / Twitter - quick text + card; great for hot takes and live posting on the day.
- Instagram - a Story with the event sticker/link plus a feed post.
- Their newsletter & email signature - a banner that links straight to registration.
- Communities - the Slack, WhatsApp, Discord groups and forums they're already active in.
If the speaker is from a company, activate the company too
Those channels are still one person's reach - but a speaker from a company is a foot in the door to that company's entire audience. Alongside the personal "I'm speaking" card, generate a co-branded creative for the company to post from its own page - "Our {name} is speaking at {event}" - and hand it to their marketing team ready to publish. Now you get the speaker's personal network and the company's followers, customers and employees.
Take it one level further with employee advocacy: the speaker's colleagues each get a one-tap "my colleague is speaking" card, turning a single speaker into a whole company's worth of advocates.
Track, then nudge
You've handed out the assets and lined up the channels - but assets handed out aren't posts published. Did they actually post on LinkedIn? If not, that's a workflow, not a dead end:
- Track posting per speaker - a simple posted / not-posted column turns "did everyone share?" into a short list of exactly who to chase.
- Multi-channel nudge - email and WhatsApp to the speaker (and their coordinator), since high-value speakers ignore inboxes on weekends.
Measure the pull
Tracking tells you who posted; measuring tells you what it was worth. Give every speaker a unique referral link or promo code so their contribution shows up in your attribution report. Speakers are competitive - "you drove the most signups of any speaker last year" is a sentence they'll want to earn again.
Steal this nudge email
Tracking, nudging, and attribution all hang off one message - so get that message right. The whole nudge is three sentences. Personal, zero-work, with the asset attached - never "please find our social media guidelines":
Subject: Your "I'm speaking" card is ready, {first name}
Hi {first name},
Your personalized speaker card for {event} is attached - your photo, your session, ready to post. One tap here posts it to LinkedIn: {share link}.
Speakers who share typically see their session fill noticeably faster, and your link tracks every registration you bring in.
See you on stage - {your name}
Send it the day they confirm, resend a variant each week with the new asset, and move non-posters to WhatsApp after two quiet weeks.
Keep them posting after the event
The talk ending is the start of the next campaign, not the finish line - and it's the moment a speaker's audience is most engaged. Don't let it go quiet:
- The minute their session ends: drop a personalized "that's a wrap" card and a short clip into their inbox/WhatsApp while the buzz is live - "great crowd at my session on {topic}." Strike while it's hot.
- Turn the transcript into content: pull each session's transcription and spin it into ready-to-post pieces - a key quote, a framework, a hot take, a 60-second clip. The speaker just approves and posts.
- Six more weeks of posts: sequence that material into roughly six weeks of post-event content, themed around your event's pillars, so the speaker keeps showing up - keeping your event top-of-mind and warming up next year's audience long after the doors close.
This is the speaker's slice of the post-event afterburn - the same engine, pointed at one of your highest-trust advocates.
Common questions
How many speakers will actually post?
With personalized assets, one-tap sharing, and scheduled nudges, plan for 60-85% of speakers posting at least once - the range speaker programs run on Premagic land in. With a generic media kit and a single "please share" email, expect under 20%. The gap is the program.
Should I pay speakers to promote the event?
No - it flips the psychology from endorsement to ad. Status and reciprocity work better: make the asset about their expertise, show them their referral numbers, and recognize the top recruiters publicly.
What if a speaker's company restricts what they can post?
Offer a company-logo variant of the card and pre-cleared copy their comms team can approve once for the whole run-up. Removing the approval loop matters more than the design.
