Email marketing is undergoing a transformation.
By 2025, the deliverability of emails is at the heart of priorities.
Ensuring that your messages reach inboxes requires a refined strategy.
Understanding the mechanisms of email deliverability involves analyzing the role of senders, gateways, and recipients. Developing an up-to-date contact list is essential to avoid bounces and improve engagement. Measuring inbox placement allows you to assess the performance of your campaigns and adjust your approaches accordingly.
The engagement of recipients is closely tied to the sender reputation. To maintain a good reputation, it is crucial to find the right sending frequency, neither too intense to avoid spam complaints nor too infrequent to be forgotten. At the same time, monitoring email KPIs such as open rates and click rates helps refine your strategies and maximize the impact of your campaigns.
In 2025, trends in email marketing include improvements in inbox security and eco-friendly initiatives in campaigns. Adopting high-performing email software is also essential; choosing from the best email software helps optimize deliverability and effectively manage your contact lists. Additionally, determining the best timing to send your emails, such as Tuesday or Thursday mornings, can significantly increase your engagement rates.
Migration to new email marketing tools should be simplified by following a comprehensive guide, ensuring a smooth transition and maintaining performance. Finally, a well-thought-out signup strategy, whether simple or double opt-in, contributes to optimizing your email list and strengthening the engagement of your subscribers. Well-structured campaigns that meet current expectations will guarantee their success and longevity in 2025.
Why is email deliverability crucial in 2025?
In 2025, email deliverability remains a major issue for marketers. With the constant evolution of anti-spam filters and the algorithms of email providers, it is essential to ensure that your messages actually reach the inbox of your recipients. Good deliverability means not only higher open rates but also a better sender reputation and increased engagement from your audience.
Deliverability directly influences the success of your email campaigns. Well-delivered emails can reinforce your subscribers’ trust, increase conversions, and improve your return on investment. In contrast, deliverability issues can lead to high bounce rates, spam complaints, and decreased visibility of your messages.
To navigate this complex landscape effectively, it’s crucial to understand the factors that influence deliverability, such as the quality of your contact list, the relevance of your content, and compliance with current regulations. In 2025, adopting a proactive and strategic approach to email marketing is essential to maintain effective and relevant communication with your audience.
How to develop an up-to-date contact list
Developing an up-to-date contact list is fundamental to improving the deliverability of your emails. A well-segmented and regularly cleaned list reduces the risks of bounces and spam complaints while increasing your recipients’ engagement. To achieve this, start by using effective signup methods, offering clear incentives and facilitating the signup process.
It is also important to implement a strategy for verifying email addresses. This includes using publithings.com/optimisez-votre-liste-email-pour-une-meilleure-engagement-et-des-resultats-optimaux”>email validation tools to ensure that addresses are active and correct. Furthermore, segmenting your list based on users’ preferences and behaviors allows you to personalize your campaigns and enhance their relevance.
To keep your list up-to-date, schedule regular cleaning operations. Remove inactive addresses and re-engage those showing signs of disengagement. By adopting these practices, you ensure not only better deliverability but also strengthen the relationship with your subscribers, thereby fostering a more effective and sustainable communication.
What are the best practices for measuring email inbox placement
Measuring email placement in the inbox is crucial for evaluating the performance of your campaigns. In 2025, various tools and techniques allow you to track accurately where your emails end up once sent. Understanding this placement helps you identify potential obstacles and adjust your strategies accordingly.
Use deliverability monitoring services to obtain detailed reports on your emails’ performance. These tools analyze metrics such as open rates, click rates, and bounce rates, providing an overview of your sending effectiveness. Additionally, conduct A/B testing to compare different versions of your emails and determine which ones achieve the best placement.
Another essential aspect is to monitor the reputations of the domains and IP addresses you use to send your emails. A good reputation promotes better placement, while reputation problems can lead to decreased deliverability. By combining these methods, you can optimize your email strategy and ensure that your messages reach their destination successfully.
Engagement and sender reputation: the keys to deliverability
The engagement of users is directly linked to the sender reputation, two essential elements for good email deliverability. In 2025, email service providers (ESPs) favor emails from reliable and engaged senders, rewarding those who maintain relevant and respectful communication with their subscribers.
To improve engagement, focus on creating quality content and personalizing your messages. Segment your audience based on their interests and behaviors to send targeted and relevant emails. The use of automation also helps maintain an appropriate sending frequency, thereby avoiding overwhelming your contacts and triggering spam complaints.
Maintaining a good sender reputation also requires rigorous management of your contact lists. Regularly remove inactive addresses and ensure that your subscribers have opted in to receive your communications. Moreover, comply with data protection regulations, such as the choice between simple or double opt-in strategy, to build trust and loyalty among your subscribers.

The actors of email deliverability: senders, gateways, and recipients
Email deliverability relies on the collaboration of three main actors: senders, gateways, and recipients. Understanding each one’s role is essential for optimizing the performance of your email campaigns.
Senders are the companies or individuals who send emails. They must maintain a good reputation by following best practices in email marketing, such as managing contact lists and sending relevant content. A sender’s reputation is evaluated by email service providers (ESPs) and directly influences deliverability.
Gateways are the technical intermediaries that facilitate the sending of emails. They ensure that messages reach the recipients’ servers securely and in compliance with established protocols. Gateways play a crucial role in filtering spam and managing IP addresses.
Lastly, recipients are the end users who receive the emails. Their interaction with your messages, such as opening, clicking, or unsubscribing, also influences your sender reputation. By monitoring and analyzing recipient behavior, you can adapt your strategies to improve engagement and deliverability.
Track key performance indicators (KPIs) in emailing
To assess the effectiveness of your emailing campaigns, it’s essential to track key performance indicators (KPIs). In 2025, the most relevant KPIs include open rates, click rates, bounce rates, and unsubscribes.
The open rate indicates the percentage of recipients who opened your email, reflecting the effectiveness of your subject lines and preheader text. The click rate measures user engagement with your email’s content, while the bounce rate signals deliverability issues by revealing undelivered emails. Finally, the unsubscribe rate indicates how many people chose to opt out of your list, which can signify issues of relevance or frequency.
For a comprehensive analysis, consult our guide to key indicators. By monitoring these KPIs, you can identify the strengths and weaknesses of your campaigns, adjust your strategies accordingly, and continuously optimize your email marketing efforts.
Email marketing trends for 2025: security and sustainability
In 2025, email marketing evolves to integrate trends focused on security and sustainability. Consumers are increasingly aware of privacy and data protection issues, prompting marketers to adopt more transparent and responsible approaches.
Improvements in inbox security play a crucial role in email deliverability. Encryption techniques and enhanced authentication, such as SPF, DKIM, and DMARC, are now essential to ensure that your messages are not intercepted or altered in transit. Furthermore, these measures contribute to strengthening the sender reputation, thus facilitating the placement of your emails in the inbox.
Additionally, sustainability is becoming a central issue. Environmentally friendly email campaigns, such as those aimed at reducing unnecessary email volume or optimizing server energy consumption, are gaining popularity. By integrating these practices, you not only improve your brand image but also contribute to the preservation of the planet.
To stay at the forefront of trends, it is important to follow advice and analyses on the evolution of email marketing. Adapt your strategies to the new expectations of consumers and technological advancements to ensure effective and sustainable communication.
Choosing the right timing to send your B2B and B2C emails
The timing of sending your emails can significantly impact their performance. In 2025, understanding the best hours and days to send emails, whether B2B or B2C, is essential to maximize engagement and deliverability.
For B2B campaigns, the best days are generally Tuesday and Thursday, with sends during the early morning hours (8 AM to 10 AM) or early afternoon (1 PM to 3 PM). These time slots often coincide with when professionals check their emails, before or after meetings.
In contrast, for B2C campaigns, sending times can be more flexible, including weekends or evenings, depending on your target audience’s behavior. It is recommended to test different sending times to identify those that generate the highest open rates and engagement.
Avoid sending emails late at night or on weekends if your audience is less active during those times. By optimizing the sending moment, you not only improve deliverability but also the relevance and effectiveness of your campaigns.
Optimize your signup strategy: single or double?
The choice between a single or double opt-in signup strategy can significantly impact the quality of your contact list and the deliverability of your emails. A single opt-in strategy means users sign up with one click, while a double opt-in requires additional confirmation by email.
Opting for a double opt-in strategy has several advantages. It ensures the validity of email addresses, reduces spam risks, and improves your list quality. By requiring confirmation, you ensure that subscribers are genuinely interested in your communications, which can increase their engagement and reduce unsubscribes.
On the other hand, a single opt-in strategy can facilitate the rapid acquisition of new subscribers but may also lead to an increase in fraudulent or unintended sign-ups. This can negatively impact your sender reputation and the deliverability of your emails.
It is therefore essential to evaluate the specific needs of your business and audience before choosing the most appropriate method. A well-suited strategy contributes to maintaining a healthy contact list and improving the performance of your email campaigns.
Optimize your email list for better engagement and optimal results
Optimizing your email list is crucial to maximize engagement and achieve optimal results in your email marketing campaigns. A well-managed list allows you to effectively target your subscribers, improve deliverability, and increase conversion rates.
Start by segmenting your list based on relevant criteria such as interests, purchasing behavior, geographic location, and engagement level. This segmentation allows you to send personalized and relevant messages, thereby increasing interest and engagement among your recipients. Use automation tools to facilitate this segmentation and effectively manage your campaigns.
Also, ensure you maintain the quality of your list by conducting regular cleanups. Remove inactive addresses, duplicates, and contacts that have not interacted with your emails for a long time. This not only improves deliverability but also reduces costs associated with sending unnecessary emails.
Additionally, analyze the key indicators related to your email list to identify trends and adjust your strategies accordingly. By optimizing your list, you ensure more effective communication and a better return on investment for your email campaigns.
Improve email deliverability after opening
After an email is opened, maintaining good deliverability relies on ongoing engagement and the relevance of your messages. In 2025, it is essential to go beyond mere opening to ensure a positive and lasting interaction with your subscribers.
To do this, personalize the content of your emails based on users’ preferences and behavior. Use automation tools to send messages triggered by specific actions, such as recent purchases or past interactions. This enhances the relevance of your communications and encourages greater interaction.
Moreover, include clear and engaging calls to action, and facilitate subscribers’ feedback by offering simple options for unsubscribing or updating preferences. By respecting your subscribers’ wishes, you build their trust and reduce the risk of spam complaints.
Finally, regularly analyze the performance of your emails post-opening by tracking metrics such as click rates and conversion rates. Use this data to refine your strategies and continuously improve the deliverability and effectiveness of your campaigns.
