System Information: Email Limits
To ensure a reliable and secure email experience for all users, Pronetsys PayGo applies rate-based limits on both incoming and outgoing messages. These safeguards help maintain service integrity and performance across our hosted email platform.
1. Email Limits Overview
-
Rate-Based Controls: Limits are measured over specific timeframes and apply to the number of messages or recipients.
-
Enforcement: If limits are exceeded, further delivery attempts may be deferred or rejected.
-
Automation and Spam: Automated email and spam are restricted under significantly stricter thresholds.
-
Right to Modify: Pronetsys PayGo reserves the right to adjust these limits at any time without prior notice to protect service quality.
2. Sending Restrictions: Domain Verification
To combat phishing and spoofing, Pronetsys PayGo enforces a domain verification check on outgoing mail.
-
Only domains associated with your customer account may be used for sending emails.
-
The system compares:
-
Authenticated User Address (used to log in)
-
SMTP MAIL FROM Address (used for message routing)
-
-
Both domains must belong to the same customer account. If not, the message will be rejected.
-
To support use cases like sending-only domains, you may add domain aliases to your primary domain within your account.
This policy significantly improves protection against spoofing and phishing, even where traditional DNS-based measures fall short.
3. Outgoing Mail Limit: 10,000 Recipients per Day
-
Daily Cap: Each user may send messages to a maximum of 10,000 recipients within a 24-hour calendar day (00:00:00 to 23:59:59).
-
Recipient-Based Counting:
-
Example: Sending 100 emails to 100 recipients each = 10,000 recipients.
-
Not based on message count, but total recipients.
-
4. Incoming Mail Limit: 400 Messages per 10 Minutes
To ensure fair system usage and prevent service degradation:
-
Each mailbox can receive a maximum of 400 messages within any 10-minute window.
-
If this limit is exceeded:
-
Additional messages are deferred, not rejected.
-
Most senders will automatically retry delivery, resulting in slight delays.
-
Examples of mailboxes impacted:
-
Diagnostic/monitoring systems
-
CRM or support platforms sending automated messages
-
Devices configured to email logs or alerts
For mailboxes expected to receive high message volumes, consider segmenting the load or contacting support for custom solutions.
