Email Campaigns: 7 Best Practices to Improve Your Deliverability
Email deliverability is a central challenge for any marketing strategy today. You can design a relevant message with an attractive offer and a polished design, but if it doesn’t reach the inbox, its impact will be nil.
In a context where the requirements of email providers like Gmail and Yahoo have become stricter, it is essential to adopt best practices to secure your dispatches and improve your performance sustainably.
Maintain a quality contact base
The quality of your contact database is one of the pillars of email deliverability. A poorly maintained database can quickly damage your sender reputation.
Invalid addresses, non-existent domains, or inactive contacts generate errors (hard bounces), which are closely monitored by email providers. In the long run, this can lead to increased filtering of your campaigns.
👉 Best practice:
Implement regular checks of your databases to identify and exclude at-risk addresses. A clean database not only improves deliverability but also optimizes the overall performance of your campaigns.
Mastering shipping volumes
Email providers analyze sending volumes and their evolution over time. A sudden spike can be perceived as suspicious behavior, even if your campaign is legitimate.
This type of variation can lead to slowdowns, filtering, or placement in spam.
👉 Best practice:
Adopt a phased rollout logic by splitting your campaign into several waves. This approach allows for smoother volumes and strengthens the trust of email providers.
Work on your email content
The content of your emails influences both deliverability and engagement. A message that is too promotional, poorly structured, or difficult to read can reduce its effectiveness.
Furthermore, certain elements (links, formatting, message weight) can impact how servers analyze your email.
👉 Best practice:
Prioritize clear, concise, and mobile-friendly messages. Include a visible call to action and ensure links are functional and consistent with your communication.
Preserve your domain's reputation
Your sending domain's reputation is a key factor in the deliverability of your email campaigns. It is built over time and depends on your sending practices.
Poor campaign management (too many bounces, complaints, uncontrolled mass mailings) can quickly degrade this reputation.
👉 Best practice:
Maintain consistency in your shipments, avoid drastic changes in volume, and adopt a progressive strategy. A good reputation significantly improves inbox placement.
Foster recipient engagement
Email providers no longer rely solely on technical criteria. They also analyze recipient behavior: clicks, opens, interactions, but also deletions or reports.
Low engagement can be interpreted as a lack of relevance in your messages.
👉 Best practice:
Segment your campaigns and prioritize active contacts. Sending the right message to the right person at the right time remains essential for maintaining a good level of engagement.
Adjust sending frequency
The sending frequency is often underestimated, even though it has a direct impact on how your campaigns are perceived.
Excessive marketing pressure can lead to unsubscribes or a decrease in engagement, which indirectly impacts deliverability.
👉 Best practice:
Finding the right balance between visibility and relevance. Adapting the frequency according to your audiences and their behavior helps to preserve the relationship with your recipients.
Measure and analyze your performance
A high-performing email campaign relies on analyzing results. Without tracking, it's difficult to identify what's working and what needs improvement.
Key indicators help you manage your campaigns and adjust your strategy.
👉 Best practice:
Track metrics such as deliverability rate, clicks, conversions, or unsubscribes. This data allows you to optimize your campaigns over time.
