1. Sign Up for an Account
Getting started is quick and simple:
- Choose a free plan (1,000 emails per month) or a paid plan suited to your volume needs.
- Subscriptions can be billed monthly or annually.
- If you send more than 3 million emails per month, our support team can assist with tailored solutions.
Important: You must use a work email or a domain-based address (for example, yourdomain.com). Free domains such as Gmail, Outlook or Yahoo cannot be used. Need a domain? Providers like Cloudflare and GoDaddy offer affordable options.
2. Set Up Your Account
Once sign up is completed, login to the app to complete these setup steps:
Verify Your Senders
Sender verification is mandatory for authorized email sending. Choose one of two options:
- Sender Domains (recommended) – Ensures SPF/DKIM alignment for better deliverability.
- Single Sender Emails – Verify individual addresses (suitable for smaller-scale sending).
Create Your Sending Credentials
You have three options for authentication:
- SMTP Users – Standard username/password authentication.
- Authenticated IPs – Secure sending via IP Authentication or Address Authentication (available on paid plans).
- API Keys – Generate API keys.
3. Start Sending Emails
