## Direct Answer
Forms help people join your list from the places you already share: your website, landing page, blog, or product.

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

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

## When To Use This Feature
- You need a signup form for your website, blog, product, or landing page.
- You want form submissions to create subscribers directly in Mailrith.
- You need tags or custom fields added when someone signs up.

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

## A Simple Setup Path
1. Decide what the form should offer and where it 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 after submission.
5. Copy the hosted link, embed code, or HTML Code and place it on your site.

## Common Mistakes To Avoid
- **Making The Form Too Long:** Every extra field adds friction. Ask for details only when they help the next email or segment.
- **Forgetting Source Tags:** A source tag makes it easier to know which form brought someone in later.
- **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.
