1. Tell them you value their opinion.
2. Inform them it’ll only take a minute.
3. Make the process painless:
3a. Send a URL that goes directly to the “write your opinion” page
3b. Keep the URL short (Use tinyURL.com if needed)
3c. Test it thoroughly to make sure it works in all major browsers
3d. Keep it to a single page and make sure it loads fast.
3e. Keep the page ad-free
4. Send them a 2nd email – the first may have gotten deleted.
