Why Connect Close to SendGrid?

Client engagement details in Close and time-tracking data in SendGrid do not align, making billing inaccurate

Close limitations compound the integration challenge: smaller integration ecosystem than major CRMs means some connections require Zapier rather than native integrations

Leads in Close and contacts in SendGrid drift out of sync, leading to outdated details on invoices, emails, and reports

Manually copying data between Close and SendGrid wastes hours every week that could be spent on revenue-generating work

Transaction data in Close requires manual verification against SendGrid, increasing audit risk

No single source of truth when contacts live in two disconnected tools, so staff second-guess which system has the correct information

Reporting across Close and SendGrid requires painful manual exports and spreadsheet merges

How We Help

With 12+ helping mid-market Australian businesses, we have built dozens of integrations between crm & sales and communication platforms. Connecting Close to SendGrid is a proven workflow we deploy in 2 weeks. On the technical side, Close uses a REST + Webhook API with API key authentication, and SendGrid authenticates via API key, which our team handles as part of the build.

Unified Leads Across Both Platforms

Leads in Close and contacts in SendGrid stay perfectly aligned. Every update, whether it is a new phone number, email change, or company association, is reflected in both systems within seconds.

Amplify Close Strengths

Close excels because built-in VoIP calling with call recording, voicemail, and power dialer means sales reps never leave the CRM to make or log calls. Connecting it to SendGrid ensures that advantage flows through your entire workflow rather than staying siloed in one tool.

Built-In Error Handling and Alerts

Our integrations include automatic retries, error queuing, and real-time notifications. If something fails between Close and SendGrid, your team knows immediately and the system self-recovers where possible.

Scalable Without Extra Headcount

As your data volume grows, the integration scales with you. No need to hire additional admin staff to keep Close and SendGrid in sync, even as your business doubles.

Close to SendGrid Use Cases

Automated error handling and retry for Close/SendGrid sync

When a sync between Close and SendGrid fails due to a rate limit, network issue, or validation error, the integration retries automatically with exponential backoff. Your team is alerted only when intervention is genuinely needed.

Sync Close leads to SendGrid contacts

When a lead is created or updated in Close, the corresponding contact record in SendGrid is automatically created or updated. Contact details, company associations, and custom fields are all mapped.

You review and approve the results before we switch to live. This approach minimises risk and ensures accuracy.

By default, we configure Close to SendGrid as a one-way sync, but bi-directional sync is possible if your workflow requires it. We will assess the best approach during the discovery session.
