Email deliverability is essential to the success of your email marketing campaigns. It measures the ability of your emails to reach your customers' inbox rather than their spam folder. CRM tools can help you centralize your data and refine your sends for better deliverability.
To ensure good deliverability, it is important to master technical aspects such as SPF, DKIM, and DMARC records, the reputation of your domain, and the quality of the content you send. Optimized deliverability drives a better open rate and inbox placement, thereby increasing customer engagement.
Faced with increasingly strict anti-spam filters, testing your email deliverability is essential. It allows you to identify issues related to delivery rates or inbox placement rate. By optimizing your content, your sending volumes, and your technical settings, you maximize your chances of success.
Discover here the best tools and tips to improve your reputation and the performance of your campaigns.
Tip no. 1: Authenticate your emails with SPF, DKIM, and DMARC
To significantly improve your email deliverability, it is essential to set up and correctly configure email authentication protocols, namely SPF, DKIM, and DMARC. These DNS records protect your domain against identity spoofing and phishing attacks, while strengthening mailbox providers' trust in your sent emails.
The Sender Policy Framework (SPF) determines which servers are authorized to send emails for your domain. DomainKeys Identified Mail (DKIM), for its part, adds a cryptographic signature to your messages to guarantee that they have not been altered during transmission. Finally, DMARC lets you specify to inboxes how to handle messages that fail SPF and DKIM checks, while providing reports on the authentication status of your emails.
An incorrect or incomplete configuration of these records can lead to poor inbox placement, or even a rejection of your emails. To avoid this, you can use specialized analysis tools that check the compliance of your SPF, DKIM, and DMARC protocols. These tools also flag whether your records are correctly aligned and authenticated, allowing you to quickly identify and resolve issues that could affect your deliverability and the reputation of your domain.
In short, customizing and regularly monitoring these protocols is an essential lever for optimizing the inbox placement rate of your email campaigns. This will allow you to maximize the impact of your email marketing strategy.

Tip no. 2: Maintain a solid domain reputation
A second tip for improving your email deliverability is to make sure you maintain an excellent domain reputation. Your domain plays a key role in the overall perception that mailbox providers have of your company.
A good domain reputation inspires trust and directly impacts your open rate as well as the inbox placement of your emails. To achieve this goal, it is essential to follow best practices such as:
- Sending relevant content that your recipients expect.
- Managing contact lists based on user permission.
- Rigorously tracking spam complaints and unsubscribe rates.
By regularly monitoring your domain reputation, you can identify and correct any issues before they affect your email marketing campaigns. This includes analyzing metrics such as:
- Open rates.
- Click rates.
- Spam complaints.
- Bounce rates.
This approach lets you continuously optimize your sending strategy.
Finally, a positive domain reputation is not limited to improving your email deliverability. It can also have a favorable impact on your search engine rankings and strengthen customers' trust in your brand.

Tip no. 3: Personalize your campaigns for more engagement
A third essential tip for optimizing your email deliverability is to put in place a strategy focused on personalization and recipient engagement. Indeed, relevant emails, tailored to your customers' interests, foster engagement through actions such as opens, clicks, or even replies.
These positive signals tell mailbox providers that your emails are wanted and not considered spam. This can significantly improve your inbox placement as well as your domain reputation.
To go further, integrating interactive elements such as polls or questionnaires will make your emails more engaging and appreciated by your subscribers. This approach strengthens their trust in your brand and encourages positive feedback, which is beneficial for your open rate and your click rate.
Finally, precise segmentation of your contact list lets you target your emails according to your customers' specific interests. This method improves engagement and optimizes the overall deliverability of your email campaigns.
Tip no. 4: Create relevant and attractive content
A key element for optimizing your email deliverability lies in the quality and relevance of your content. Well-designed and engaging content helps improve the open rate, drive clicks, and reduce spam complaints. Make sure your emails are clear, personalized, and tailored to your recipients' specific expectations in order to maximize the impact of your email marketing campaigns.
To attract attention in the inbox, it is essential to optimize the layout, use catchy email subject lines without falling into wording that could be perceived as spammy, and include visible and relevant calls to action. A smooth user experience, both in terms of design and reading of your emails, encourages your customers to interact more. This sends a positive signal to mailbox providers and strengthens the reputation of your domain.
Finally, vary the content you send and regularly test its performance using email deliverability analysis tools. These analyses will help you quickly identify what works and what does not, thus allowing you to adjust your messages to avoid anti-spam filters and improve your inbox placement rate.

Tip no. 5: Control your volumes and keep your lists clean
The fifth key tip for maximizing your email deliverability is to manage your sending volumes well while maintaining the quality of your mailing lists. Indeed, sending a large number of messages at too fast a pace, especially from a new domain or to a list that has not been cleaned, can arouse the suspicion of mailbox providers. This increases the risk that your emails will be filtered or rejected.
To avoid this, adopt the practice of IP warming. This method consists of gradually increasing your sending volumes in order to build a positive reputation with recipient inboxes.
At the same time, it is important to regularly monitor the health of your mailing lists. Eliminate invalid addresses, quickly handle bounce errors, and remove inactive addresses or those that generate too many spam complaints. A clean and qualified list not only improves your delivery rate, but also reduces the bounce rate and limits the risk of spam placement. This promotes better inbox placement while ensuring an optimal user experience for your customers.
In short, rigorous management of your lists and your sending volumes is essential to sustainably optimize your email deliverability. It also helps preserve mailbox providers' trust in your email campaigns.
