Write an event invitation

I work in marketing at an insurance broker. Help me write an invitation to our event.

Context: Seminars for commercial clients work best on a risk they already fear, such as cyber, flood or a director's personal liability, often with an insurer or loss adjuster speaking.

Before you start, ask me for anything missing from this list:
- The event, date, place or link
- Who it is for
- What they will leave knowing
- How to book

Then:
1. Lead with what the reader gets from attending.
2. Give the practical details in one block.
3. Write a reminder for the week before and the day before.

Give me:
- The invitation
- Two reminders
- Subject lines for all three

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general information about insurance only. Never say that a particular person or business is covered, never suggest a claim will be paid, and never call a price the cheapest or the best.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our compliance officer or whoever approves financial promotions should see:
- That the invitation list has consent to be contacted
- The insurer or speaker's permission to use their name and logo
- Whether the invitation promotes a product and needs approval
