The email subscribe form is about as annoying as it is useful, especially if you haven’t thought of a way to prevent it from being abused by spambots and automated systems programmed to sign up and input bogus data.
At Enform, we reckon double opt-in and captcha safeguards are by far the most common security features against this problem, but they’re not exactly perfect.
What Can Spambots Do?
More often than not, spambots are merely annoyances, filling up your subscribers lists with fake information—easily removable. There are, however, times when spambots can leave spamtrap email addresses on your lists, which can be a nightmare to fix.
While we’ve built Enform’s Automailer to have sufficient defences against these issues, it still pays to know a fewDIY-style remedies against spambots.
CaptchasDo More Harm than Good
Captchas, those computer-generated images with codes users have to type in, are a good way to protect your subscribe forms from spambots, but they also end up penalising innocent users who simply want to complete a form.
In email subscribe lists, this translates to fewer signups due to the inconvenience of captches; in your zeal to eliminate spambots, you end up hitting genuine signups too. Think about it, you don’t want to keep jumping through hoops when filling up a form.
Here are much simpler alternatives to traditional captchas.
