Overview

Email

Infobip Email is a cloud based, all-in-one communication solution suited to both transactional (opens in a new tab) and marketing message delivery. Use Email to create rich, personalized, and responsive emails using the easy-to-use drag and drop email editor.

Email messaging is a simple way for ad-hoc one-way communication, or more advanced template management, scheduled sending, or communication flows for one-to-one and one-to-many.

Email Main Flow

This solution includes reporting, which allows you to create reports around basic statistics, such as open rates, click-through rates and more. Send emails over the web interface, HTTP API or SMTP. See more information in Technical Specifications.

Use the drag and drop email editor to easy build good looking emails. Add buttons, images, HTML. Adjust layouts and style. And customize and preview emails for any device.

Templates

Build templates and use them as many times as needed to save time and remain consistent. The editor supports the building of rich templates in the UI or through HTML, and send them over the web interface or API.

Personalization

Seamlessly personalize emails for each of your customers using attributes and place holders. Send dynamic content using handlebar helps within your HTML content, and define placeholder parameters.

Journey flows

Use the visual flow builder to create journeys quickly, and re-use them at any time for recurring campaigns. Define targeted customer journeys and trigger sends based on certain events at the right moment.

Manage Subscriptions

Manage subscriptions automatically using the built-in footer functionality. Unsubscribe contacts are automatically detected and moved into specific lists so as to no longer include in campaigns.

Tracking

Collect service quality feedback and customer engagement insights by tracking several events. Capture delivery stats, bounce rates, spam reports, link clicks, opens and unsubscribes.

Manage Suppressions

View and edit suppressions caused by hard bounces and user complaints. Quickly narrow the data down to a single record using powerful filters, and share suppression data user access across all of your accounts.

Image handlingAll images, regardless of size, are handled with an external link and can be downloaded when the email is opened. No images are embedded into the content of the email.
Request rate limitThe maximum number of emails you can send from a single account within a specific time frame depends on various factors, including:
  • Email size: For smaller emails Infobip can provide higher throughput. The total size of each email, including attachments, is capped at 25MB.
  • Request complexity: The complexity of the request itself, such as the amount of data.
  • Server capacity: The server's ability to handle requests is a primary factor. This includes CPU, memory, and network bandwidth.
  • Network latency: The time it takes for a request to travel from the client to the server and back can affect the perceived speed. High latency can slow down request processing.

The precise sending limits and throughput capacity may vary. Detailed information regarding the number of requests per second can be provided per account.

Set up a domain

Once you upgrade your account to a paying account, you need to set up a domain or subdomain with which to send emails. That domain is the address that appears in the From field for your recipients.

If you have an existing domain, it is recommended to use a subdomain. This minimizes the potential impact other traffic might have on your main domain. Using subdomains allows you to segment your email activities, which can help identify and resolve any issues more efficiently. It also protects your main domain's reputation by isolating different types of email traffic. You can still send emails as the main domain when using a subdomain.

If you do not have the domain set up yet, contact your hosting provider to supply it for you.

For more information about domains, see Register a new domain.
