Landing in Spam to Better Email Deliverability

Sink or Swim? Deliverability Health Decides Cold Email Fate
Email delivery can be tough to crack. Each factor brings its own set of challenges.
Spam Traps
When these filters tag your emails, they prevent them from reaching their intended destinations, compromising deliverability.
IP & Domain Reputation
If past spam Sparkle have tarnished your IP address or domain’s reputation, your delivery rates could suffer.
Sender Authentication
To maintain trust with ISPs, emails need proper authentication. If your authentication isn’t strong, ISPs might discard your emails, negatively affecting deliverability.
Low Engagement Rates
Low engagement can suggest to ISPs that your emails aren’t important or look like spam, reducing your email deliverability rate.
Frequency & Volume
Bombarding recipients with email can strain your credibility and activate spam filters. This may result in lower engagement and threaten your deliverability.
Deliverability Monitoring and Feedback Loops
Regularly monitor your deliverability metrics and set up feedback loops with ISPs. This allows you to receive real-time data on issues like spam complaints, enabling timely adjustments to improve deliverability.
