Why Email Deliverability Deserves Your Attention
With 306.4 billion emails sent and received daily in 2021 per Radicati Group, the competition for inbox real estate is fierce. Standing out matters.
Poor email deliverability hampers metrics:
- Opens & clicks plunge: Messages routed to spam or tabs beyond primary inbox get ignored. Deliverability issues severely limit visibility and reader engagement.
- Conversions lag: Emails not making it to the inbox can‘t convert readers. These placement problems translate directly to revenue.
- Contacts disengage: Subscribers who signed up but rarely see your content feel forgotten and ignore future emails or unsubscribe outright.
It‘s not enough just to hit send. You must optimize every factor influencing successful subscriber inbox delivery in order to fully capitalize on email‘s performance potential.
Key Elements That Impact Email Deliverability
Many variables affect whether a message gets flagged as wanted content for the inbox or filtered as low-priority, spam or even blocked entirely. Core factors include:
Sender Reputation Score
ISPs assign a reputation ‘score‘ between 0 – 100 evaluating your sending credibility. According to SparkPost, domains scoring:
- 90+ earn excellent inbox placement
- 80-90 face occasional filtering
- Under 70 will be labeled as spam
Engaged subscribers and responsible sending practices strengthen this over time while problems plummet your score quickly.
Contact List Quality
If your recipient list includes addresses that continuously bounce or frequently mark messages as spam, ISPs start broadly assuming your emails deserve extra scrutiny or limits.
Email list cleanliness is mandatory for good standing. Ongoing hygiene measures like removing stale entries, monitoring engagement levels, and re-confirming opt-ins should anchor your efforts.
With a shared IP setup, other tenant actions on the server impact association to your domain. But choosing a dedicated IP assigns send reputation directly allowing you to isolate your deliverability.
2022 Validity IPS Insights research found dedicated IP users enjoy:
- 17% higher inbox rates
- 13% lower spam rates
Avoiding ‘Honey Traps‘
So-called ‘spam traps’ or ‘honey traps’ refer to email addresses specifically setup to identify and blacklist questionable senders. Traps catch senders still contacting inactive addresses or patterns of failed deliveries.
Proactively detecting and removing traps alongside general list cleaning limits these risky recipients in your database.
