An event invitation is a message that tells the recipient what is taking place, when and where, and asks them to confirm their attendance.<\/strong> It can be a formal letter, an email or a card, and its success is measured in confirmations.<\/p>\n\n

Today, most are sent by email. It’s fast, lets you include a registration button that leads to a landing page<\/a> and tells you who has opened it.<\/p>\n\n

What is an event invitation?<\/h2>\n\n

It is the official communication about an event<\/strong>: a conference day, a congress, a product launch, a training session or a company dinner. It has a twofold job. It gives the practical details and convinces the reader that it’s worth saving that slot in their schedule.<\/p>\n\n

It is not the same as a save the date<\/em>. A save the date<\/a> only asks guests to block off the date, weeks or months in advance. The invitation comes later, with the agenda, the venue and the link to register.<\/p>\n\n

Invitation letter or invitation email: which should you use?<\/h2>\n\n

Both serve the same purpose, but they don’t suit the same situations.<\/p>\n\n

<\/th>Invitation letter<\/th>Invitation email<\/th><\/tr><\/thead>
Format<\/td>Paper or PDF on letterhead<\/td>HTML or plain-text email<\/td><\/tr>
Tone<\/td>Formal, ceremonial<\/td>Formal or friendly, depending on the audience<\/td><\/tr>
When to use it<\/td>Officials, speakers, official ceremonies<\/td>Customers, partners, students, employees<\/td><\/tr>
Confirmation<\/td>By phone or written reply<\/td>Registration button or direct reply<\/td><\/tr>
Measurement<\/td>Can’t be measured<\/td>Opens, clicks and registrations<\/td><\/tr><\/tbody><\/table><\/figure>\n\n

In practice, many organizations combine the two: a formal PDF letter<\/strong> for institutional guests and an email<\/strong> for everyone else. If you need the more formal version, this guide on how to write a formal email<\/a> will help.<\/p>\n\n

What should an event invitation include?<\/h2>\n\n

A good invitation answers the guest’s questions before they ask them.<\/p>\n\n

\"The<\/figure>\n\n
    \n
  1. Event name<\/strong> and who is organizing it.<\/li>\n\n\n\n
  2. Date, start and end time.<\/strong> If it’s online, state the time zone.<\/li>\n\n\n\n
  3. Venue or access link<\/strong>, with the full address or the platform.<\/li>\n\n\n\n
  4. Reason to attend:<\/strong> what they will learn, who they will meet or what they will gain.<\/li>\n\n\n\n
  5. Agenda summary<\/strong> or the main speakers.<\/li>\n\n\n\n
  6. How to confirm<\/strong>, with a deadline and a single button or link.<\/li>\n\n\n\n
  7. Contact<\/strong> for questions and, if needed, dress code or accessibility information.<\/li>\n<\/ol>\n\n

    Point 6 is the one most often forgotten. Without a clear call to action<\/a> and a deadline to confirm, many replies end up as “I’ll let you know.”<\/p>\n\n
