Beyond the Content: Sender Reputation

Even a perfect email can land in spam if the sender's reputation is poor. Here are key factors that email providers consider:

Email Authentication (SPF, DKIM, DMARC)

These are DNS records that prove your emails are legitimate and not forged. They are crucial for deliverability.

  • SPF: Specifies which IP addresses are allowed to send email for your domain.
  • DKIM: Adds a digital signature to your emails to verify they haven't been altered.
  • DMARC: Tells receiving servers what to do with emails that fail SPF or DKIM checks.

IP & Domain Blacklists

Spam filters check if your sending IP or domain is on a known blacklist. Being listed is a major red flag. Domain age also matters; newer domains face more scrutiny.

More factors that impact your email deliverability

Deliverability is a complex component, and thehre are many reasons it can be impacted. These are some of the most common issues you’ll likely run into at some point in your email marketing journey.

1. Sender reputation

Your sender reputation is like a grade or score for your domain or IP. It’s built over time based on how recipients interact with your emails through opens, replies, complaints, bounces, and more.

A good reputation means more of your emails land in inboxes. A bad one? Straight to spam. To protect yours, send quality content, avoid sending too many emails too fast, and stay off blacklists.

2. Email authentication: SPF, DKIM, and DMARC

Email authentication helps prove your messages are real and not spam or phishing attempts. There are three key protocols:

  • SPF (Sender Policy Framework): Verifies who’s allowed to send emails for your domain.
  • DKIM (DomainKeys Identified Mail): Adds a digital signature to confirm your email hasn’t been tampered with.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance): Tells mail servers how to handle messages that fail SPF/DKIM, and gives you visibility.

Tip: Make sure all three are properly set up for your domain. Try our free SPF record or DMARC record generators.

3. Blacklist issues

Email blacklists are databases of IPs or domains flagged for sending spam. If you’re on one, your emails may get rejected or land in spam, no matter how great your copy is.

Check regularly to stay off trouble lists. If you’re listed, investigate the cause and fix it before requesting removal.

4. Domain age

Brand-new domains are under more scrutiny because spammers often use them to dodge detection. If you’re emailing from a fresh domain, expect extra filtering.

That’s why domain warm-up matters: Gradually building up sending volume and engagement helps you build trust with inbox providers.
