Email your list again after months of silence

Help me email my list again after a long gap.

My business: [what you do]
When I last emailed: [roughly]
How people joined the list: [e.g. sign-up form, customers]
What's happened since: [news, changes, new things]
How often I can realistically send: [e.g. once a month]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A comeback email, sent only to people who agreed to hear from me: a light reminder of who I am and why they're getting it, one useful thing, and an easy way to unsubscribe.
2. Three subject lines.
3. A short second email for two weeks later.
4. A realistic schedule with themes for the next 3 months.
5. When to remove people who never open.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts or results. UK English, warm, no grovelling.
