## Direct Answer
Forms let people join your list from places you already use, such as your website, landing page, blog, or product.

- Collect email addresses and only the custom fields you need.
- Assign tags when someone submits the form.
- Use hosted links, embed code, or HTML Code based on where the form should appear.

## What This Feature Helps You Do
- **Subscriber Capture:** A form gives people a clear way to join your list without requiring you to add them manually later.
- **Cleaner Subscriber Data:** Collect the right fields and tags at signup so each subscriber record is useful from the start.
- **Simple Website Embeds:** Use Mailrith forms on existing pages instead of building your own signup backend.

## When To Use This Feature
- Use forms when you need a signup form for your website, blog, product, or landing page.
- Use forms when submissions should create subscribers directly in Mailrith.
- Use forms when tags or custom fields should be added at signup.

## When This May Not Be The First Thing To Set Up
- Do not start with forms if you need a full public page with copy, layout, sections, and reporting. Use landing pages for that.
- Do not publish the form until you know what people receive after submitting it.
- Do not collect data you will not use. Shorter forms are usually better.

## A Simple Setup Path
1. Decide what the form should offer and where the form will appear.
2. Create the tags and custom fields the form should use.
3. Add the email field and only the extra fields you need.
4. Choose the success message or redirect that appears after submission.
5. Copy the hosted link, embed code, or HTML Code, then place it on your site.

## Common Mistakes To Avoid
- **Making The Form Too Long:** Every extra field adds friction. Ask for subscriber details only when they help the next email or segment.
- **Forgetting Source Tags:** A source tag makes it easier to see later which form added a subscriber.
- **Skipping The Follow-Up:** Plan the first email, sequence, or automation before people start submitting the form.

## How This Connects With The Rest Of Mailrith
- Tags can be assigned when someone submits the form.
- Custom fields collect details beyond name and email.
- Segments can group subscribers who joined through a form.
- Landing pages can include forms when you need a hosted signup page.
