Tips to Improve Email Deliverability
Email deliverability is a cornerstone of successful marketing campaigns. Ensuring your emails land in recipients' inboxes—and not in spam folders—requires a strategic approach and careful avoidance of common mistakes.
This guide outlines five frequent email deliverability pitfalls and provides actionable steps to help Uppush users optimize their campaigns for maximum engagement and success.
1. Mismatch Between Sender Address and Dedicated Sending Domain
The Mistake:
Using a sender address that doesn’t match the root domain of your dedicated sending domain. It means that the "From" email address used in your emails does not align with the primary domain (root domain) you have configured for email sending.
Let's breaking it down:
What Is a Sender Address?
The sender address is the "From" email address visible to your email recipients. For example:
What Is a Dedicated Sending Domain?
A dedicated sending domain is the domain configured in your email service provider (like Uppush) to send marketing or transactional emails. It ensures that your emails are sent from an authenticated source, improving deliverability. For instance:
If your business domain is
yourdomain.com, your emails should ideally be sent from email addresses like[email protected].
Why It Matters:
Email providers like Gmail and Yahoo use domain alignment to verify the authenticity of your emails.
A mismatch between your sender address and your dedicated domain raises red flags for mailbox providers, increasing the likelihood of your emails being marked as spam.
How to Fix It:
Ensure your sender address (e.g., [email protected]) aligns with the root of your dedicated sending domain (e.g., yourdomain.com).
Verify that your SPF, DKIM, and DMARC records are properly configured for your domain. Uppush provides detailed guides to help you set up these records.
2. Sending to All Segments at Once
The Mistake:
Sending the same email to all segments of your audience, regardless of their behavior or relationship with your brand.
Why It Matters:
Irrelevant emails can lead to higher unsubscribe rates, lower engagement, and spam complaints.
Targeted communication fosters better engagement by addressing the specific needs and preferences of each segment.
How to Fix It:
Segment your audience based on factors such as:
Purchase history (e.g., frequent buyers vs. first-time visitors).
Engagement level (e.g., highly active vs. dormant subscribers).
Demographics or location.
Create tailored messages for each segment. For example:
Send exclusive offers to loyal customers.
Share introductory discounts with new subscribers.
Use Uppush’s segmentation tools to automate and refine your audience targeting.
3. Neglecting to Warm Your Sending Infrastructure
The Mistake:
Starting to send high volumes of emails from a new sending infrastructure (ESP, IP address, or domain) without proper warming.
Why It Matters:
Mailbox providers view sudden spikes in email volume as suspicious, especially from new domains or IP addresses.
Warming gradually builds a positive sender reputation, ensuring higher inbox placement.
How to Fix It:
Start Small: Begin by sending emails to a hyper-engaged audience (e.g., subscribers who’ve opened or clicked emails in the past 30 days).
Gradually Scale Up: Increase your sending volume by 10-20% every few days.
Track Engagement: Monitor metrics like open rates, click-through rates, and spam complaints to adjust your strategy.
Refer to Uppush’s detailed email warming guide for step-by-step instructions.
4. Failing to Clean Your Mailing List Regularly
The Mistake:
Continuing to send emails to inactive or unengaged subscribers without regularly cleaning your list.
Why It Matters:
Unengaged subscribers lower your engagement metrics (e.g., open rates), signaling to mailbox providers that your emails aren’t valuable.
Sending to inactive contacts wastes resources and can result in higher costs for email campaigns.
How to Fix It:
Audit Your List: Identify subscribers who haven’t engaged in the past 60-90 days.
Run Re-Engagement Campaigns: Try to win back inactive subscribers with special offers or surveys.
Suppress Non-Responsive Subscribers: Remove or suppress users who remain unengaged after your re-engagement efforts.
Use Uppush’s tools to automatically manage and clean your list based on activity.
5. Sending to Subscribers Who Haven’t Engaged in Over 365 Days
The Mistake:
Emailing users who haven’t interacted with your brand or emails for more than a year.
Why It Matters:
Subscribers inactive for over 365 days are unlikely to re-engage via email.
Persistently emailing these contacts increases the risk of spam complaints and negatively impacts your sender reputation.
How to Fix It:
Set an Engagement Window: Focus on subscribers who’ve engaged within the last 90-180 days.
Explore Other Channels: For contacts inactive for over a year, use alternate marketing channels such as SMS, social media, or retargeting ads to rekindle interest.
Automate Suppression: Use Uppush to automatically suppress subscribers who exceed your engagement window.
Best Practices for Deliverability Success
1. Authenticate Your Domain
Ensure your domain is authenticated with SPF, DKIM, and DMARC to prove your emails are legitimate.
2. Monitor Your Metrics
Keep an eye on:
Open Rates: Indicate how well your subject lines and content resonate with your audience.
Click-Through Rates (CTR): Measure engagement with your email content.
Spam Complaints: A high complaint rate signals issues with targeting or content.
3. Respect Frequency and Timing
Avoid sending too many emails in a short period, which can overwhelm subscribers.
Send emails at times when your audience is most likely to engage, such as during lunch breaks or in the evening.
4. Prioritize Quality Over Quantity
Focus on sending fewer, more relevant emails to engaged subscribers rather than maximizing volume.
5. Stay Compliant
Always include an unsubscribe link in your emails to comply with regulations like GDPR and CAN-SPAM.
Use clear sender information to build trust with recipients.
