During a support for your emailing strategyOne of our customers asked us about the technical limits to the volume of emails sent from an Outlook mailbox. In this article, we share with you the answer we gave him. While these limits do exist, there are other points of vigilance to consider.
Outlook's technical limitations
According to Microsoft support siteThe technical limits for sending e-mails via Outlook are as follows :
- Daily recipients: 5,000
- Maximum number of recipients per message: 500
- Daily recipients outside the relationship: 1,000
Remarks :
- An "unrelated recipient" is someone you've never sent an email to before.
- Limits may vary according to usage history and will be lower for non-subscribers.
- Sending limits for third-party connected accounts depend on the service provider.
Technical limits do not mean good practice
It's important to distinguish between technical limits and good practices. The volume of emails a person sends will depend on the type of emails sent. For example, are they automated or manually written emails? by a sales representative? If the content of an e-mail generates complaints, Outlook can reduce the authorized volume, or even block the mailbox. This can have an impact on the whole company if it's a business mailbox. You'll need to work hard on message writingthe targeting and pace of solicitations.
Prefer emails in text format to HTML
Some companies want to send "aesthetically pleasing" commercial emails from their Outlook inbox. Some even create their commercial email from an email builder and copy and paste it into Outlook. But Outlook is not an e-mail system like any other. These emails very often encounter display problems, such as white lines in the middle of the email.
We recommendsend emails in text format rather than HTML. To make your message clearer, focus on the hierarchy of information, line breaks, line breaks, the color of alternative text, bulleted lists, bolding, etc. There are many ways to make an email fluid and pleasant to read, as shown in the example below:

Reading content isn't everything. The best way is to talk to us.
Include BIMI in prospecting emails
As can be seen in the example above, the logo displayed next to the sender with a blue checkmark allows recipients to check that this is not a phishing email, and to verify the seriousness of the sender. Here's how, the shipper has set up the BIMI protocol (Brand Indicators for Message Identification). This is an email-related authentication technical specification that enables companies to enhance the security of their domain names by displaying the company logo next to their sender name.
Using BIMI adds a level of confidence in the sender, particularly useful in the field of commercial prospecting, where the risk of spam is very high.
Conclusion of Badsender
In short, beyond the technical limitations to keep in mind, it's crucial to focus on the interest of the commercial message, its writing, the prioritization of the email and the use of BIMI. It may also be worth exploring tools such as Lemlistwhich specialize in B2B prospecting and integrate well with Office365. Companies whose sales reps want to follow up customers in small batches often use Lemlist. They have a marketing routing tool for their newsletters and marketing automation.
