Deliver the emails your users depend on with Sendzovo's transactional email infrastructure, built around authenticated sending, API and SMTP connectivity, and delivery-focused workflows.
Email delivery is more than submitting an email from your application. A complete delivery workflow includes message submission, authentication, delivery attempts and the response from the recipient's mail system.
Your application should focus on your product instead of maintaining mail servers and delivery infrastructure. Sendzovo provides the email infrastructure between your application and your recipients.
Connect your application directly to Sendzovo over HTTPS and send transactional email programmatically.
Use standard SMTP when your application, framework or existing email library already supports SMTP delivery.
Configure your sending domain before sending production email. Authentication gives receiving mail systems signals they can use to verify that your messages are authorized.
Publish the required DNS configuration to identify authorized sending infrastructure for your domain.
DKIM signing provides receiving systems with a mechanism to verify the authenticity of messages associated with your domain.
Add a domain-level authentication policy that builds on SPF and DKIM and helps receiving systems handle authentication failures.
Verify your DNS configuration before using the domain for production email sending.
Your sending identity is part of every email your application sends. Configure the appropriate sender information for your application and authenticated domain.
Define the address that recipients see as the sender of your transactional messages.
Use a recognizable sender name so users can quickly identify messages from your application.
Use an authenticated domain that is configured for your email infrastructure.
Where supported, configure the address that should receive replies from your recipients.
An API request is only the beginning. A message moves through several stages before the recipient's mail system accepts or rejects it.
Your application creates a transactional message containing the recipient, sender, subject and message content.
Submit the message to Sendzovo through the Email API or SMTP service.
The message enters the email delivery workflow and is prepared for delivery to the recipient's mail system.
The message is submitted to the recipient's mail infrastructure.
The recipient's mail system may accept the message or return a delivery-related response.
Delivery activity can be used to understand the outcome of your sending workflow and investigate problems.
A successful API request does not necessarily mean the recipient has received the message. Separate submission from final delivery when designing your application workflow.
This distinction is important when your application needs reliable status information for password resets, account verification, receipts, notifications and other product-critical messages.
Delivery visibility helps you understand what happened after your application submitted an email.
Your application successfully submitted the message to the email delivery service.
The recipient's mail system accepted the message for delivery.
The message could not be delivered to the recipient and a bounce response was received.
A delivery attempt encountered a failure that prevented successful delivery.
Delivery generally means the recipient's mail system accepted the message. It does not guarantee that the email will appear in the primary inbox rather than spam, promotions or another mailbox location.
When delivery event webhooks are enabled for your Sendzovo account, you can connect email activity to the workflows already running in your application.
Repeatedly sending to addresses that cannot receive your messages can create unnecessary delivery problems. Use bounce and complaint information to make better sending decisions.
Identify addresses where messages could not be delivered and investigate the reason for the failed delivery.
Complaint activity can indicate that recipients do not want messages from a sender and should be treated carefully.
Suppression workflows can help prevent future messages from being sent to addresses that should no longer receive them.
Delivery information gives your team useful context when investigating individual sending failures or recurring delivery issues.
Some delivery problems start with the recipient address. Email verification helps you evaluate addresses before they enter an important sending workflow.
Evaluate addresses using available syntax, domain, MX, disposable and mailbox-related signals.
Identify addresses that may require additional attention before sending.
Send the messages your application needs to communicate important information to users.
Password resets, email verification, account activation and security notifications.
Notify users about activity, events, changes and important actions inside your application.
Deliver purchase confirmations, receipts, booking information and other transactional messages.
Send automated operational and application-generated messages from your backend systems.
Communicate subscription changes, account events and other service-related updates.
Power transactional email for SaaS products, ecommerce platforms, marketplaces and internal applications.
Combine authentication, verification, sending and delivery monitoring into a workflow designed around reliable application email.
Bring the essential pieces of application email together instead of maintaining separate systems for every part of your sending workflow.
Choose a programmatic Email API or standard SMTP depending on how your application is built.
Configure your sending domain with the authentication records required by your email setup.
Evaluate recipient addresses before sending to reduce avoidable address-related problems.
Build application workflows around password resets, notifications, receipts and other important messages.
Keep recurring transactional email content organized and separate from application logic.
Integrate email into your existing application stack without rebuilding your own email infrastructure.
Build your email workflow with the Sendzovo features that fit your application.
