To engage your targets effectively, Pubrio sequences support multiple outreach channels such as email and LinkedIn. Connecting the right credentials for these channels is essential to execute your campaigns smoothly and within platform limits.
Connecting Credentials
- In your sequence settings, click the + button to add a new credential.
- Select the relevant channel you want to connect, such as Email or LinkedIn.
- Follow the guided steps to authenticate and grant necessary permissions. These permissions allow Pubrio to represent your identity securely and send outreach on your behalf.
- It’s important to carefully follow the permission guidelines to ensure proper connection and avoid errors.

Understanding Rate Limits and Credential Usage
- Each credential has its own rate limits that control how many outreach actions can be performed within a given time period.
- When multiple sequences use the same credential, Pubrio prioritizes engagement based on the earliest added targets.
- Targets added later will be queued and their actions delayed until the rate limit resets.
- This rate limiting mechanism prevents overactive engagement that could harm deliverability or trigger platform restrictions.
- Managing multiple credentials or aliases allows you to distribute outreach volume, maintain consistent engagement, and avoid hitting limits.

Example: Rate Limit in Action
Imagine you add 100 targets to a sequence and send outreach messages to all at once. Sending too many emails simultaneously signals email providers and may cause your messages to bounce or be marked as spam. To prevent this, Pubrio enforces rate limits per credential.
- By default, Pubrio delays each email by 10 minutes (600 seconds) between sends.
- We recommend sending between 50 and 100 emails per day per credential to maintain healthy deliverability.

Best Practices
- Connect all relevant channel credentials before launching sequences to ensure smooth multi-channel engagement.
- Monitor credential usage and add aliases if needed to increase throughput without risking rate limit blocks.
- Regularly review permissions and re-authenticate credentials as required to maintain uninterrupted outreach.
Proper credential management is a foundational step to maximize the power of Pubrio’s multi-channel sequences while respecting platform limits and maintaining high deliverability.
