Office 365 email marketing without SaaS

If your organization prefers an on-premises or private-server setup, nuevoMailer provides email campaign software that you host yourself. You keep control over data, IPs, and compliance while still using Exchange Online for sending.

What is Microsoft Graph?

Microsoft Graph is a comprehensive API that provides access to a wide range of Microsoft services, including Outlook, OneDrive, SharePoint, Teams, and more. Compared to SMTP / IMAP / POP3 it offers the following benefits:

• Security: Unlike SMTP or IMAP, which require storing and transmitting email credentials, Microsoft Graph API uses OAuth 2.0 for authentication. This means your credentials are never directly exposed, reducing the risk of unauthorized access. OAuth 2.0 provides a secure and standardized way to handle authentication, which aligns with modern security practices.
• Access Control: With Microsoft Graph API, you have fine-grained control over the permissions granted to the application. You can limit access to only what is necessary for processing email bounces, minimizing potential security risks.
• Compliance: Microsoft Graph API is built with enterprise security and compliance in mind. It complies with various industry standards and regulations, ensuring that your data is handled securely.

Is MS Exchange suitable for email marketing?

It depends. Microsoft strongly recommends that for bulk mailing that includes sending legitimate newsletters to your readers, you should use a specialized service such as Amazon SES, MailGun, Postmark or similar. However, for smaller volumes and email marketing Office 365 use cases, MS Exchange can work fine for campaigns, transactional, and trigger emails.

Therefore if you want to send a few million emails within a day MS Exchange may not be the best solution. But for a few thousand emails per day it can work perfectly fine. Here are the sending limits for Office 365 which as you can see are quite generous for most small and mid-sized businesses.

Consider also that you can use MS Exchange along with other sending methods nuevoMailer offers by creating several Sender profiles.

What about Office 365 Exchange Online APIs?

The MS Graph API - nuevoMailer integration covers everything you need related to sending, reading and processing emails. It is broader than the Office 365 API. It provides a unified experience, simpler management, extensive documentation and further scalability.

Can the MS Graph API be used with Exchange on-premises?

We have not tested this case. According to Microsoft it can be done under a hybrid deployment but with certain limitations and considerations.
