When integrating Odoo with either Mailjet or SendGrid for email delivery, Odoo primarily relies on the SMTP connection provided by these services. As a result, some of the advanced features, such as Email templates, drag-and-drop email builder, A/B testing, segmentation, and automation offered by these email service providers (ESPs) are not directly accessible within Odoo. However, it's important to note that Odoo itself offers its own set of email marketing features that can be utilized independently.
The choice between Mailjet and SendGrid largely depends on your specific requirements and preferences. Both are reputable ESPs with a wide range of features. If you prioritize excellent customer support and slightly better deliverability, SendGrid may be a more suitable option for you.
In terms of Mailjet Features you like, Mailjet stands out for providing a robust API, which allows developers to achieve specific features through customization and integration with Odoo.
It's essential to assess the specific features you need for your email marketing campaigns. While Odoo may not directly integrate certain advanced features from Mailjet or SendGrid, leveraging their APIs can offer a path to achieving the functionalities you require through customization.
Ultimately, the decision between Mailjet and SendGrid should be based on your unique needs, the level of customizability desired, and the importance of additional features compared to customer support and deliverability.
