Top Tips to Avoid Spam Filter While Sending Emails
The world of mail deliverability can be a depressing place. Even the most seasoned and rule-abiding mail marketers will experience delivery issues and (unintentionally) send spam Emails.
In this post we share some of our best recommendation to ensure that your 10 minutes avoid spam filters and get delivered to your recipients’ inboxes. For supplementary information and explanation on the tips below, check out entire Tips & Tricks to Stay Out of the Spam Folder Guide.
Build your OWN mail list
What you mention in your mails is incredibly important, but your content doesn’t mean anything if you’re saying it to the wrong or to an unengaged audience. Always, try to avoid:
Renting, picking up, or co-registering an mail from a third party
Sharing or adopting a shared list with partner
Scraping mails—if you’re running a robot to collect Emails, known as email harvesting, this practice puts you squarely into the spam camp. Do not usually do it!
Organically building your mail list is a long-term play that will contribute to your email program. It won’t be the simplest or the fastest way to grow your list, but, it will be the most effective.
Provide double opt-in
When you’re building an email list of new subscribers, consider how you will verify that your recipients want to receive email from your brand. We suggest using a double-opt-in methods that provides a subscriber with a welcome email that they must confirm (usually check a box that says they agree to 10 minutes) before they officially end up on your email list.
Having subscriber use double opt-in indicates that they have a genuine interest in your Emails (which will keep your engagement and deliverability rates high). Read more about the various types of mail opt-in and why double opt-in is preferred in our blog post, You Forgot to Say Please: How to Collect mail Addresses.
Authenticate your mail with the SPF, DKIM, and DMARC
Email authentication can be tricky, but, it’s simplest to remember that authenticating your email verifies that you are who you say you are and that you’re sending legitimate email. Inbox providers, like Google and Yahoo, trust authenticated email more and are more reasonable to deliver mail from authenticated email into the inbox.
The following method authenticate your temp email address and turn out to the inbox providers that your email is worthy of the inbox and not the spam folder:
Sender Policy Framework (SPF) – assure you are who you say you are by comparing the sender’s IP (found in the domain’s DNS record) with a list of IPs authorized to send from that domain.
Domain Key Identified Mail (DKIM) – meeting this standard assure that the email was not tampered with during transmission.
Domain-Based Message Authentication Reporting and Conformances (DMARC) – leveraging the strength of both SPF and DKIM, DMARC require both to pass in order to send and deliver email.
The technique above are the responsibility of the sender, but SendGrid can help you with each. Learn more about how our professional service can support you mitigate deliverability issues and help set your email program up for success.
Regularly clean your 10 minutes address lists
Some of the recipients will naturally unsubscribe from your email list, but put in mind that many who no longer want to receive your email will simply ignore your Emails instead of unsubscribing. This is indeed harmful, because the lower your email engagement rate, the less favorably you will be viewed by the ISPs. This means your Emails are more reasonable to go to the spam folder.
Combat low engagements by periodically removing unengaged users, bounced 10 minutes, and role email addresses. Your mail list is going to encounter some amount of churn. Don’t hold it personally! Be proactive, clean your list and you’ll start experiencing improved email deliverability rates.
Avoid blacklist and monitor your reputation
Your mail domain has a reputation associated with it and if it slips or you send an email to a spam trap email, you may discover yourself on an email blacklist. Unfortunately even tentative and well-intentioned senders may find themselves on a blacklist.
Reduce the risk of finishing on a blacklist by considering some of the following practices:
Using the confirmed opt-in or the double opt-in
Carrying out the sunset policy to remove unengaged subscribers
Using real-time address validations—if someone enter in a false email (or even a typo) and you send temp email address to that invalid email address, your sender score suffers.
Keeping an eye on your delivery rate will advise you of any signals that you may be on a blacklist. For more information on blacklist, read for the Avoiding Blacklists: Best Practice For Reducing Your Risk of IP and Domain Blacklisting.
Provide the preference center
A preference center allows new subscribers and existing subscribers to choose how regularly they receive your 10 minutes. They further reduce the risk of your subscribers marking your Emails as spam by putting them in control over the type of content they receive from you and when.
Provide a direct and prominent preference center to reduce friction and the risk of irritating your recipients. As an end, you’ll see higher engagement rates… which helps maintain your Emails from going to spam!
There are many types of preference centers so learn about what type is best for your email program in our blog post.
Monitor the 10 minutes engagement metrics
Tracking your email performance and engagement metrics is the merely true way to know if your email program is improving or if some changes are needed. But, before you control, it’s important to develop some baseline metrics so you have a consistent picture of your email performance.
The following metrics are a great place to start:
Don’t panic if you set up to notice negative trends, just be to sure to act quickly once you do. For illustration, if your open rates are starting to dip, review your subject lines and email frequency as those two variables are likely affecting this metric.
Email marketing is far from basic and no matter how hard you try, finding perfection is a fleeting goal. But that doesn’t mean you can’t go close! Following the tips above position your email program to go on its best. Always keep in mind that the greater your email engagement, the more likely your email will end up where it is intended and not get caught in spam filters.
