Corporate event invitations: the UK B2B playbook

Sending a corporate event invitation is a different game from a consumer wedding invite. The stakes are higher, the guest list is harder, and any whiff of spam or "consumer tool" branding damages your company's credibility.

This playbook covers what a professional UK corporate invitation looks like in 2026, and how to get the operational details (VIP, EAs, dietary) right without it becoming a logistical nightmare.

The three things corporate guests actually care about

1. Is this legitimate? Does the email come from a real person at a real company? Does the domain look trustworthy?
2. Is it easy to say yes or no? Single tap, pre-filled name, easy forward to EA if needed.
3. Do I have all the info I need? Date, venue, timing, dress code, agenda, any dietary choices.

Everything else is execution detail.

Why sending from "your company" matters (not a third-party sender)

If your corporate invitation email arrives from [email protected] or [email protected], three things happen:

• Corporate spam filters flag it. Delivery rate drops 30-50%.
• Senior guests question whether the event is real.
• Your brand takes a credibility hit that's hard to recover from.

The fix: send from your own corporate domain via Outlook or Google Workspace. Insendy's Corporate tier does this via Outlook OAuth, invitations arrive from {yourname}@{yourcompany}.com, not a third-party sender.

VIP tracking: why it matters for B2B

In a corporate event, not all guests are equal. You'll have:

• Tier 1 VIPs: board members, key clients, industry dignitaries. You need to know immediately if they've accepted.
• Tier 2 important guests: senior partners, major clients, press. Worth a follow-up if they haven't replied in 2 weeks.
• Standard invitees: the bulk of your list. Standard RSVP workflow.

A good corporate invitation platform lets you tag VIPs on the guest list, filter the dashboard to VIPs only, and see their status at a glance.

Executive Assistant forwarding (the overlooked feature)

Senior UK corporate guests rarely manage their own calendars. A CEO, CFO, or managing partner will have a PA or EA handling their diary. If your invitation doesn't make it easy for the guest to forward to their EA, you lose them.

What EA forwarding should look like:

1. The senior guest receives the invitation
2. They tap "Forward to EA" and enter their EA's email
3. The EA receives the full invitation context, clearly marked as "RSVP on behalf of [senior guest name]"
4. The EA's response is logged in your dashboard against the senior guest, with the EA credited as the responder

Insendy's Corporate tier has this as standard. Most consumer platforms don't.

Menu selection and dietary reports

Corporate catering works on tight margins and bigger numbers. Getting the headcount wrong by 10% can mean thousands of pounds in waste or an embarrassed caterer.

Your invitation platform should collect:

• Menu choice per course (if plated)
• Standard dietary tags: vegetarian, vegan, gluten-free, halal, kosher, dairy-free, nut-free
• Free-text field for specific allergies or religious requirements
• Per-guest visibility (so the caterer can match choices to seating)

Export should be one click to CSV, formatted cleanly for your caterer's system.

Agenda and programme display

For events longer than dinner, guests want to know the schedule up-front. Include:

• Arrival window (e.g., 18:00-18:30)
• Welcome / drinks time
• Programme highlights (speeches, awards, entertainment)
• Dinner start time
• Carriage time or end-of-event
• Transport arrangements if applicable

Make it updateable, plans change, and you don't want to resend a new invitation just because the schedule shifted by 15 minutes.

What goes wrong in corporate invitations (and how to avoid it)

Problem: Invitation lands in junk folder

Fix: Send from your corporate domain, not a third-party sender. Configure SPF/DKIM/DMARC properly.

Problem: Senior guests never reply

Fix: Enable EA forwarding. Most don't reply because they can't be bothered to forward manually.

Problem: Dietary info scattered across 80 email replies

Fix: Collect dietary in the RSVP form with standard tags, not free-text. Export as a single report.

Problem: Caterer needs final numbers, VIPs haven't replied

Fix: Tag VIPs early, set a separate earlier deadline for their response, chase by phone if needed.

Problem: Event date moves, you have to resend

Fix: Use a platform where you can update the date in place, the shareable link stays the same, only the content changes.
