Email bot spam is a type of email spam that uses automated programs to send unsolicited messages to users. These messages are often filled with malicious links and can lead to computer infections, theft of personal data or identity fraud.

Spambots attack email marketing campaigns, causing damage to the reputation of the sender, and decreasing the deliverability of their emails. They also make it difficult for email marketers to use their tools to measure results, which can be important for improving email marketing campaigns.

Using an unsubscribe link in your email signature is a great way to prevent spambots from signing up for your mailing lists. Some of these bots will scour the internet looking for signup forms, so making sure your emails are easy to find and that your subscribers have an easy option to remove themselves from your list is a good idea.

The Impact of Bot Spam on Email Marketing and How to Prevent It

Replacing the @ symbol with (at) is a common trick for harvesting email addresses. It makes it easier for spambots to find your real address, which increases the chances of you receiving a lot of junk mail.

The Donbot botnet is one of the biggest sources of spam today, sending out more than 800 million messages per day. It is a particularly clever botnet, as it has a variety of different networks that each push their own spam content.

Another spambot attack tactic is to use URL shortening, which reduces the size of the email message and increases the chances that someone will click on it. MessageLabs, which tracks spam, notes that this change is particularly effective for image spam.
