From data security and compliance to deliverability, we've got you covered
High sending capacity
Whether you have to scale sending capacity quickly, send a high volume of seasonal or cyclical emails, deliver on the fly or use dedicated IPs, image and/or content hosting, you're subject to the ever-changing sending/receiving rules and throughput limits of individual ISPs.

Cakemail manages the sending and reporting of millions and millions of emails, structured in a variety of ways, ensuring data security and compliance every time.
Shared or dedicated sending IP addresses
By default, Cakemail sends email from IP addresses shared with other Cakemail clients. Shared addresses are a great option for many clients who want to start sending immediately with established IPs. And clients who want to manage their own IP reputation can even rent dedicated
IP addresses.
Ensure you maintain a consistent brand experience
Sender branding
Fully customize the name and email address people see when they receive emails from you to ensure better delivery of your emails and maintain a consistent brand experience.
Link branding
Even the little details can have a big impact on your brand, which is why Cakemail allows you to use your domain name in the redirect links we use to track subscriber activity.
Branded dynamic templates
Create a single design source for all your transactional emails. Use Cakemail's tag library or your own custom attributes to send subscriber-specific content for every
type of transaction.
Getting your emails delivered
Email authentication
Authentication is a way of showing that the sender is who they say they are, which is key when you're saying that Cakemail has permission to send email on your domain’s behalf. We support shared or dedicated DKIM, SPF/SenderID and DMARC methods of authentication and we encourage our clients to do the same to ensure a high rate of delivery.
Unsubscribe management
Letting people choose the emails they do and don't want receive helps maintain a healthy relationship between you and your customers. Cakemail ensures unsubscribes request are honoured promptly and will prevent additional emails from being delivered to these recipients.
Bounce management
Proper bounce management is critical to email deliverability and maintaining your reputation. When an email cannot be delivered, Cakemail automatically processes bounce messages and ensures future emails are not being sent to these addresses.
Feedback loop management
Cakemail is partnered with more than a dozen ISPs, which allows us to unsubscribe anyone who's marked an email as spam from all future mailings. This helps to protect your sender score and maintains our network reputation as one of the best in the industry.
Managed deliverability
Cakemail manages deliverability for you, ensuring that every email reaches every recipient's Inbox and that your sending domains don’t get blocked or blacklisted by ISPs.
