However, it is crucial to understand and manage the limits and restrictions imposed by each provider to ensure the smooth operation of your applications. Below are the limitations and guidelines for interacting with supported providers: ### **LinkedIn** These limits are conservative recommendations. Exceeding them can result in HTTP 429 or 500 errors. Ensure your system handles such errors gracefully to avoid warnings or account restrictions related to automation. **Connection Requests (Invitations):** - Free accounts: ~**100** invitations/week (~15-20/day) with a 200 character message. - Paid accounts: ~**100-150** invitations/week (~20-25/day) with a 300 character message. - Accounts with Sales Navigator/Recruiter: ~**150-200** invitations/week with a 300 character message. **Rules & Restrictions:** - You can only send invitations to **1st, 2nd, or 3rd-degree connections**, or if you share a group. - LinkedIn may require an **email address** for certain profiles (outside of your immediate network). - Invitations without personalization are more likely to be ignored and can affect account trust. **Messaging Limits:** - You can only send **direct messages to 1st-degree connections.** - To reach non-connections, you need **InMail credits** (available on Sales Navigator/Recruiter). - Typical daily safe limits: - Direct messages: ~50–60/day/account. - Comments: ~20–30/day/account. - Likes/Reactions: ~100–150/day/account. You can only send **direct messages to 1st-degree connections.** To reach non-connections, you need **InMail credits** (available on Sales Navigator/Recruiter). **Profile Retrieval:** - Free accounts: ~**100-300** profiles/account/month. - Paid accounts: ~**2000** profiles/account/month. - Accounts with Sales Navigator/Recruiter: ~**5000+** profiles/account/month**.** **Search Results:** - Free accounts: Approximately ~**100** per search. - Paid accounts: Approximately ~**1000** per search. - Accounts with Sales Navigator/Recruiter: Additional ~**2500+** per search. **Other Actions:** - Limit to **actions/day/account** for activities such as posts likes(**~100-150**), messaging(**~50-60**), comments(**~20-30**). ### **Gmail (Google)** **Sending Limits:** - **Standard Gmail accounts:** Up to 500 emails per day. - **Google Workspace accounts:** Up to 2,000 emails per day (official limit). **Recommended Sending Limits:** - Limit sending to **50–100 emails/day** for Gmail, and **100–150 emails/day** for Google Workspace for best deliverability. - For new accounts, start with **20–50 emails/day** and gradually increase. - Use multiple domains/aliases to distribute sending reputation (see[Google support](https://support.google.com/a/answer/7502379?hl=en)). - Monitor bounce rates and engagement to avoid throttling or blocks. ### **Microsoft (Outlook / Office 365)** **Sending Limits:** - Microsoft 365 subscribers can send up to: - **5,000 recipients per day** - **500 recipients per message** - **1,000 non-relationship recipients per day** (recipients you haven’t emailed before) - Limits for non-subscribers are generally lower. Limits for third-party connected accounts depend on the service provider. (See [Microsoft support](https://support.microsoft.com/en-us/office/sending-limits-in-outlook-com-279ee200-594c-40f0-9ec8-bb6af7735c2e)) **Recommended Sending Limits:** - We advise following Gmail’s conservative sending limits for safety. ### **CRM Integrations** | **Provider** | **API Rate Limit** | **Notes** | | --- | --- | --- | | Pipedrive | 100 requests per 10 seconds per company | [Pipedrive API Docs](https://pipedrive.readme.io/docs/core-api-concepts-about-pipedrive-api) | | Salesforce | 100,000 API calls per 24 hours (per org) | [Salesforce API Docs](https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/resources_limits.htm) | | Zoho CRM | 250 API calls/minute, 50,000/day (Enterprise) | [Zoho API Docs](https://www.zoho.com/crm/developer/docs/api/v2/api-limits.html) | | HubSpot | 100 API calls per 10 seconds per app/account | [HubSpot API Docs](https://developers.hubspot.com/docs/api/usage-details) | **Best Practices:** - Distribute API calls evenly throughout the day. - Monitor for HTTP 429 (rate limit) errors and implement exponential backoff/retry logic. - Use batch requests for bulk operations and respect concurrency limits. - [Getting Started](https://help.b2brocket.ai/getting-started?hsLang=en#main-content) - [All Users](https://help.b2brocket.ai/getting-started?hsLang=en#all-users) - [White Label Users](https://help.b2brocket.ai/getting-started?hsLang=en#white-label-users) - [Contacts](https://help.b2brocket.ai/contacts?hsLang=en) - [Campaigns](https://help.b2brocket.ai/campaigns?hsLang=en) - [Mailboxes](https://help.b2brocket.ai/mailboxes?hsLang=en) - [Settings](https://help.b2brocket.ai/settings?hsLang=en) - [Additional Guides](https://help.b2brocket.ai/additional-guides?hsLang=en#main-content) - [Important Documents](https://help.b2brocket.ai/additional-guides?hsLang=en#important-documents) - [AI Agent Learning Hub](https://help.b2brocket.ai/additional-guides?hsLang=en#ai-agent-learning-hub) - [Release Notes](https://help.b2brocket.ai/additional-guides?hsLang=en#release-notes) - [Troubleshooting](https://help.b2brocket.ai/additional-guides?hsLang=en#troubleshooting) [![B2B Rocket Logo (primary)-1](https://help.b2brocket.ai/hs-fs/hubfs/B2B%20Rocket%20Logo%20(primary)-1.png?width=250&height=51&name=B2B%20Rocket%20Logo%20(primary)-1.png "B2B Rocket Logo (primary)-1")](http://b2brocket.ai) [mailto:support@b2brocket.ai](mailto:support@b2brocket.ai) Copyright © 2026, B2B Rocket
