A newsletter subscription form is the simplest, most reliable way to grow your contact list with people who actually want to hear from you. Mailpro builds the form for you in three clicks — you copy the embed code into your website and contacts start landing in your account, complete with double opt-in, GDPR consent timestamps and any custom fields you choose.
Build the form in 3 clicks
1. Open Lists → Subscription forms → New form. 2. Pick the destination list, the fields to collect (email is required, the rest is optional), and toggle Double opt-in on (recommended). 3. Customize colors, button text, success message and click Generate. Mailpro returns three things: an embed code, a hosted URL and a QR code.
Add the form to your website
Three options depending on your stack:
- HTML embed: paste the <iframe> or <script> snippet anywhere in your page. Works on any platform.
- WordPress: install the Mailpro WordPress plugin and select your form from a dropdown. No copy-paste required.
- Hosted URL: link a button anywhere (header, footer, social bio) to the Mailpro-hosted form page. Useful for landing pages and bio links.
Best practices for high-converting forms
1. Keep it short — ask only for email at first; collect more fields after the confirmation. 2. Make the value clear — «Get our weekly digest» beats «Subscribe to newsletter». 3. Show the form above the fold on your homepage. 4. Always enable double opt-in for compliance and list quality. 5. Customize the confirmation email so it doesn’t look generic. See double opt-in subscription.
Where the data goes
Every submission lands in the destination list as a contact, with consent timestamp, IP and source URL recorded automatically. If a contact already exists, the new fields update the existing record without duplication. The visitor receives the double opt-in confirmation email immediately.
