Don't use [at] [dot] to try and hide your email.

Using "[at]" and "[dot]" in place of "@" and "." respectively in an email address can sometimes be done to prevent automated email address harvesting by spam bots. However, it's not always effective, as many bots are programmed to recognize and interpret such substitutions. Additionally, it can make it more difficult for legitimate users to understand and correctly enter the email address.

For better protection against spam, it's usually more effective to use methods like:

1. Create a contact form on your website instead of displaying the email address directly.

2. Implementing form CAPTCHA or other verification methods to ensure that only humans can submit the contact form.

3. Utilizing email filtering and spam protection tools provided by email service providers.

4. Being cautious about where you share your email address online, especially on public forums or websites where it can be easily scraped by bots. Thats why you should use a tool like VeilMail.io to hide email address with captcha

Ultimately, while replacing "@" and "." with "[at]" and "[dot]" may offer a small degree of protection, it's not a foolproof solution and may inconvenience legitimate users. It's often better to employ other strategies to mitigate spam while maintaining accessibility for genuine communication.
