Advanced Integration Tips

Setting Up Double Opt-In

Double opt-in is a great way to confirm subscriber intent while staying compliant with GDPR guidelines. To set this up, create a confirmation email that includes your logo, a clear call-to-action, and a concise explanation of what happens next. Once the subscriber clicks to confirm their email, you can configure Sendinblue to redirect them to a custom thank-you page. After confirmation, take things a step further by organizing your leads using scoring and tagging to better manage and segment your audience.

Contact Scoring and Tags

With Sendinblue, you can use contact scoring and tagging to prioritize and segment leads based on their form responses and engagement levels. For example, you can assign scores for factors like budget, company size, or urgency, and then map these scores to Sendinblue's custom attributes. Once a contact reaches a specific score threshold, you can trigger automated workflows to engage them further. These scoring techniques not only help with segmentation but also make it easier to integrate data across platforms.

Multi-Platform Data Sync

After setting up robust opt-in and scoring systems, ensure your data syncs effortlessly across all your tools. To achieve this, connect Sendinblue with your other marketing and CRM platforms. Here’s how to make it work:

• Use webhooks or Sendinblue's API to enable real-time data syncing.
• Match Reform fields to Sendinblue attributes for consistent data mapping.
• Set up alerts to catch issues like API rate limits, field sync errors, or duplicate entries.

Next Steps

Before launching, make sure everything works as expected by running multiple test submissions. This helps confirm that all form data - including custom field mappings - is correctly transferred to your Sendinblue contact lists. For detailed instructions, check out the Testing section.

Once the initial setup is verified, shift your focus to ongoing performance monitoring. Regular checks are key to keeping your integration running smoothly. Here's a quick breakdown of what to monitor and how often:

Keeping an eye on these areas ensures your setup stays stable and helps you evaluate how well your strategy is working. If you run into technical issues, double-check your API keys and field mappings, or reach out to support for help.

To refine your integration further, consider these steps:

• Plan quarterly audits to review your setup.
• Keep a record of successful tests for easy reference during future audits.
• Set up alerts to flag unusual submission patterns.

You can also take your strategy up a notch by using progressive profiling across different touchpoints. This method helps you gather detailed contact profiles while keeping form completion rates high.
