Bring Your Own Key
Why Standard Plan Uses Your Own Email API Key
Standard and Business plans send emails through your own email service provider account — not QubrixMail's infrastructure. Here is why this is better for you.
The Problem With Shared Sending
When multiple businesses share one email sending infrastructure, one bad sender can hurt everyone's deliverability. Spam complaints from one user affect the shared IP reputation that other users depend on.
Your Own Infrastructure = Better Deliverability
When you bring your own API key:
Your emails go out from your own sending account
Your domain's reputation is yours to build and protect
One bad actor elsewhere cannot affect your delivery
You have direct access to your provider's analytics
It Costs You Almost Nothing
All supported providers offer free tiers. For most small businesses, these free tiers are more than enough.
| Provider | Free Tier |
|---|---|
| Resend | 3,000 emails/month free |
| SendGrid | 100 emails/day free |
| Mailgun | 1,000 emails/month free |
| Brevo | 300 emails/day free |
