Send spam test emails

Your team works hard at creating email with good content and sharp designs, so it would be a shame if they ended up in spam folders. Sending spam test emails to the various mail clients is an important step in getting your message to the inbox.

Get more emails delivered to the inbox

When you send a spam test email before your big send, you’ll learn how to tweak your email messages so they make it through to their target inbox. Every email service provider like Google’s Gmail has a different spam algorithm, so your test emails need to be thorough. Doing it yourself can be complicated and time-consuming. To simplify the process, you might consider working with a company that can help you send test spam messages.

Why sending spam test emails is important

It’s one thing for your email marketing messages to go into your recipients’ spam folder. But if you’re also regularly getting marked as spam, it could land your IP address or domain name on a global blocklist. Having clean emails is also good for your business. By having your emails scanned in advance by the major spam filters, you can improve your open rates, keep customers engaged, and achieve your marketing goals. Running your emails through the most well-known spam filters like SpamAssassin, and finding out which aspects of your email messages might trigger them can be very valuable information as you scale.

DIY spam tests

If you wanted to try running a spam test on your own, you could open free email accounts with Google, Yahoo, Microsoft, and other popular email service providers. Then you’d have to send a test email to each account to see if your messages show up in the inbox, or get flagged. This is all fine if you have a small email list and don’t send emails out very often. But as you grow, it will slow down your productivity. On the other hand, using a service will automate the process for you, plus give you valuable insights like your spam score, if you’re blocklisted, and advice on how to tweak your content.

Avoid spam filters and send email messages with confidence

Making minor changes to the subject line, message body, and HTML coding might seem easy enough. For instance, it’s pretty certain that if you use a word like “viagra,” you’re going to be caught in the spam filters. However, sometimes, your spam status is not because your content is actual spam, but is based on more complex issues, like the metadata or the SMTP server behind the scenes. For example, if you don’t have a recipient list comprised of real emails, that alone can raise red flags. Furthermore, you want to make sure that your recipients don’t report you for sending unsolicited bulk email. By building your list so that it only contains people who opt-in to receive your content (and not purchasing names and email addresses from unknown entities), you can stay one step ahead of spammers. That’s why in addition to sending spam test emails, working with an email validation service provider to make sure the email addresses you have are valid is another important step to take if you want to protect your sender reputation.
