My newsletter is in promotion

Have you ever had that problem? Have you ever had your business revenue drops because of spam placements? Do you dread the promotion tab?

If this ever happened to you, you’ll love us. We’re fixing this email problem once and for all. Inboxbooster fixes email in spam and promotion.

Why are you in spam?

Senders are in spam for a combination of:

  • Incorrect Email DNS Setup. The keywords are DKIM, SPF, and DMARC.
  • Bad Reputation. Mailbox providers score IPs and domains from their past behavior.
  • Content Filter, the content of your emails triggers the filters.

Usually, the root cause is a combination of these factors, and they compound. For instance, your DMARC is wrongly set up and triggers Gmail to send all your emails to spam. Because nobody is marking the email as "not spam," Gmail decides that your email is spam. Now your domain and your content have a bad reputation. You fixed your DMARC, but your emails are still going to spam because of what happened.

How does Inboxbooster fix spam placements?

Spam filters work by scoring how people interact with your emails. Once in spam, your emails are interacted with much less. Hence they tend to stay in spam. This is this vicious cycle that Inboxbooster breaks.

We resolve this quandary by identifying the elements in your email triggering the spam filter and the root cause.

The first step is to send us your email: we’ll tell you where you’re in spam, promotion, and if you have any DNS issues. This is free.

Then we’ll build a step-by-step solution guide with the root cause, the short-term fix, and the long-term fix.

Also, we love talking to you, so please book some chat time with us.
