SENDZOVO GUIDE
From adding your first sending domain to sending transactional email and monitoring delivery, this guide walks through the essential Sendzovo setup from start to finish.
Sendzovo is a transactional email platform for applications and websites. You authenticate a domain, choose SMTP or the Email API, send your messages, and use Sendzovo to monitor delivery and recipient health.
Send transactional messages over HTTPS using a Sending API key.
Connect existing applications and SMTP-compatible software without rebuilding your mail integration.
Check recipient addresses using Sendzovo's verification tools and dedicated Verification API credentials.
Follow message activity, delivery outcomes, bounces, suppressions and spam complaints from the dashboard.
Create a Sendzovo account and sign in to the dashboard. The dashboard provides the tools for domains, message activity, verification, templates, webhooks, testing and billing.
Open Domains in your dashboard and add the domain that your application will use to send email.
After the domain is added, Sendzovo takes you to its setup screen where ownership and sending DNS can be configured.
Domain authentication establishes that you control the domain and configures the DNS records needed for authenticated sending.
Sendzovo checks the authoritative nameservers for your domain. When a supported DNS provider is detected, the dashboard can offer an automatic setup option.
Authorize the detected provider and Sendzovo can progress through ownership verification and the required sending DNS configuration. The setup screen shows progress until the domain is ready.
You can always configure DNS manually. Copy the Host and Value shown by Sendzovo into your DNS provider exactly as displayed, then return to Sendzovo and choose Check ownership or Check / Continue setup.
Once your domain is ready, use either a Sending API key or SMTP credentials to connect your application.
Message Streams let you organize sending within a domain. Streams can have their own sending credentials, activity and analytics, making it easier to separate different application or transactional workloads.
Choose the integration method that best fits your application. Existing applications can usually use SMTP, while new integrations may prefer the REST API.
For request fields, code examples and detailed integration information, use the Developer Documentation.
Sendzovo includes email verification tools for checking recipient addresses. Verification API credentials are separate from your Sending API keys.
A detailed verification endpoint is also available at
/v1/verifyEmailDetailed. Manage Verification API keys
from the Email Verification area of your account.
Use Templates & Layouts to build reusable transactional email content. Templates help keep common messages consistent while allowing application data to be inserted dynamically.
Use Email Activity and domain analytics to follow messages after submission. Sendzovo records recipient-level processing and delivery outcomes so you can investigate individual messages as well as broader sending performance.
Use the Suppressions and Spam Complaints areas to understand addresses that should not continue receiving email and to protect sender reputation.
Delivery Health provides another view of sending quality and helps you identify issues that may require attention.
Webhooks let your application receive Sendzovo events without repeatedly polling the dashboard. Add and manage webhook endpoints from the Developer section of your account.
Use Sendzovo's testing tools to confirm that your domain, credentials and integration work as expected before moving application traffic to production.
Use the Billing area to view available plans, your billing history and other billing options enabled for your account. Your dashboard shows the features currently available to you.
Once your domain is authenticated and your application is connected through SMTP or the Email API, use Email Activity, Delivery Health, verification and webhooks to keep your transactional email workflow observable and reliable.
