Introduction: Navigating the Evolving Email Marketing Landscape
Email marketing remains a highly effective channel, delivering an average ROI of $42 for every $1 spent according to DMA. However, deliverability is becoming increasingly complex with changing spam filters and global privacy regulations. This guide aims to provide email marketers with the latest tactics to maximize inbox placement in 2023.
We'll cover factors like IP reputation, sender authority, email authentication, content relevance, and list growth. Common pain points include low deliverability, lack of automation, and insufficient customer support. Platforms like Sensorpro provide solutions through comprehensive deliverability tools, workflows, and dedicated support.
By following best practices around reputation, authentication, optimization, and monitoring, marketers can overcome obstacles and ensure their messages consistently reach the inbox. Let's explore the key steps for deliverability success.
Key Factors Impacting Email Deliverability
Achieving excellent deliverability requires getting the basics right across four core areas:
IP Reputation
The reputation of your sending IP addresses significantly influences deliverability. Here are best practices for keeping your IPs in good standing:
-
Gradually warm up new IPs by starting with low email volume and increasing the quantity sent over several weeks as engagement and complaints are monitored. This prevents sudden spikes that may trigger spam filters. Services like MailboxValidator offer automated IP warming.
-
Maintain high engagement rates like open and clickthroughs before aggressively scaling message volume. Prioritize relationship-building over short-term growth.
-
Use dedicated IPs for different audience segments and campaign types to isolate reputation. This allows ongoing testing and optimization.
-
Monitor key metrics including spam complaints, bounces, and unsubscribes. Analyze any deliverability declines and refine approaches.
Methods for Building IP Reputation
-
Start with small volume mailings and increase gradually over several weeks.
-
Ensure consistently high engagement rates before ramping up volume.
-
Use dedicated IPs for different audience segments and campaigns.
-
Monitor key metrics like spam complaints, bounces, unsubscribes.
Sender Reputation
Your domain and branding reputation also impacts deliverability. Follow these practices to develop sender authority:
-
Regularly scrub lists and segment based on engagement to maintain relevancy. Remove inactive subscribers and spam traps.
-
Personalize content and provide subscriber value through relevant recommendations and insights.

DKIM cryptographically validates emails are not altered during transit.
-
DMARC aligns SPF and DKIM to prevent spoofing and verify legitimacy.
