How to Use Expandi to Follow Up LinkedIn Event Attendees

The short answer: if you hosted or attended a LinkedIn event and want to reach the people who signed up, Expandi pulls up to 1,000 attendees per event link into a campaign on a $99-a-month Business seat, but a new seat's gradual warm-up allows only 5 to 21 actions a day, so a 300-person list takes about four working weeks to receive every connection request (event list article, warm-up article, pricing page, checked on 26 October 2026). The steps: switch on the warm-up, build the event attendees list, create a connector campaign with a 7-day wait before the follow-up, write or approve the messages, set limits and a start date, and activate.

Work out three things before step 1:

1. The calendar. For example, if every warm-up action is a connection request, days 1 to 12 allow 2 x (5 + 8 + 11 + 14 + 17 + 20) = 150; the other 150 of a 300-person list take 150 / 21 = 7.1, so 8 more days. That is 20 active days, by the ramp in the warm-up article.
2. What the event already gives you. You need no CSV and no scraped list: the attendee list exists on LinkedIn, and Expandi reads it from the event's link if you attended or created the event, per the event list article.
3. The reading that says it worked. Acceptance on the connection step, then replies to the first follow-up. Write both down after the first 50 requests and compare them with the next 50.

The job rewards speed. A follow-up that names the event reads as a conversation rather than a pitch, and it reads that way only while the event is recent. Plans and prices are in the Expandi glossary entry.

What you need

• A Business seat, or the 7-day trial, which includes every feature and starts without a charge, per the homepage FAQ.
• The LinkedIn profile that attended or created the event, connected to Expandi with the right country, since each account gets a dedicated IP address from that country, as the IP article explains.
• The event's URL.

Know whose risk this is before you start. The attendees signed up for an event, not for an automated sequence, and section 8.2 of LinkedIn's User Agreement bars both bots that send messages and any attempt to bypass or circumvent its use limits. If LinkedIn objects, the restriction lands on the profile that sent the messages.

Step 1: Switch on the warm-up

Open the LinkedIn account menu, then LinkedIn settings, then LinkedIn account limits, and choose the gradual 14-day warm-up. It waits until a campaign is active, shows "Starts with your first campaign" until then, and pauses without losing progress if every campaign stops, according to the warm-up article. Set your active days and hours under Activity schedule settings as well; tasks only go out inside them.

Step 2: Build the attendee list

Open the event on LinkedIn and copy its link. If you are the event's admin, click View as member first and copy that URL, which ends in ?viewAsMember=true; otherwise the search returns nothing. In Expandi, go to Lead lists, click +Add leads, choose Event attendees URL, paste the link and name the list. Two options are worth ticking: Auto-refresh, which reloads the list on a schedule as more people register, and Auto-assign, which drops the list into a campaign once it is ready. One list holds up to 1,000 people, and it works for past and future events, per the event list article.

Step 3: Create a connector campaign

On the My campaigns page, click +Add new campaign, enter a goal such as "book a call with attendees who run a sales team" or skip it, choose Connector, select the event list and click Open in builder, as the campaign guide describes. The preset flow visits the profile, sends the request and waits on an "If connected" condition. Set that wait to at least 7 days: the guide's tip is that a shorter delay drops people who accept late, and they never get the follow-up. A request that is not accepted is withdrawn automatically, per the campaign types article.

Step 4: Write the messages, or approve an agent's draft

Name the event in the connection note and in the first follow-up, and ask one question that the session raised. Keep the second follow-up for people who accepted and stayed silent.

If your account has the MCP beta, an agent can write the first draft. In Expandi, go to Account Settings, then AI agents, choose Claude and copy the server address; in Claude, add it under Settings, Connectors as a custom connector, then sign in to Expandi and authorise, following the Claude connection article. Give it the event title, your offer and two past messages in your own voice, and ask for a connector campaign draft for the attendee list. The MCP page says the agent only drafts and never activates a campaign or edits a running one, so a person reads every step in the builder and rewrites anything that would not survive being read aloud to the attendee. The Logs tab under AI agents records what the agent did and on which account, per the MCP log article.

Step 5: Set limits, priority and a start date

In the campaign's Settings tab, set how many people enter the first action each day, the campaign priority, and a start date if the follow-up should go out on a particular morning. Every active campaign shares the account's general limits, so a second campaign slows this one. Sentiment analysis, which reads replies with AI to judge interest, can run on one campaign at a time, per the campaign guide.

Step 6: Activate

Click the toggle beside the campaign name on My campaigns. Expandi schedules the tasks and starts sending about 45 minutes later, inside your active times, per the activation article. A grey toggle on a builder campaign means a blocker in the flow; fix it and try again.

What Expandi's help centre warns about

• Touching the warm-up. Switching it off and on, or editing its settings, sends the limit back to its starting value, per the warm-up article.
• A range that starts at 0. The daily limits article warns that some days will then send nothing.
• Oversized campaigns. A campaign holds 5,000 leads and an account runs 15 active campaigns at once, per the limitations article.
• The Mobile Connector as a shortcut. It needs two-factor authentication, and once LinkedIn's weekly limit is reached, mobile requests stop for two weeks, according to the Mobile Connector article.

What the trial covers, and what the pricing page adds

The free check comes first. At the warm-up's pace, the trial week sends at most 5 + 5 + 8 + 8 + 11 + 11 + 14 = 62 requests, so sort the attendee list and put the 62 people who matter most at the top; their acceptance rate is a fair reading of the event's goodwill before any invoice. If you would rather not automate at all, those 62 can go out by hand from LinkedIn in an afternoon.

Read the plan page with the help centre open beside it. Expandi's pricing page lists "Campaign Types that Allow Bypassing Outreach Limits" as a Business feature, with the Mobile Connector adding 100 connection requests a week, while the Mobile Connector article says it no longer bypasses LinkedIn's weekly limit and adds between 50 and 100. The bigger number helps sell the seat; the profile that tests it is yours.

FAQ

How many attendees can one event list hold?

Up to 1,000 per event attendees URL list, from past or future events, per the event list article.

Can I invite my connections to the next event from Expandi?

Yes. The Event Invite campaign invites first-degree connections to an event you host or attend, according to the campaign types article.

Will the AI agent send messages on its own?

No. Through the MCP it drafts campaigns and replies; you launch the campaign and approve each reply, per the MCP article.
