FAQ on Data Residency for EU

To get started with Data Residency for Email, create a subuser designated for the EU. Assign an EU-based dedicated IP address and configure your sending domains. To learn more, see the guide on creating an EU regional subuser.

By default, Twilio provisions Pro, Premier, and Custom plan accounts with global dedicated IPs for all accounts, including those based in the EU.

To get an EU-specific IP:

• Self-serve
  Direct SendGrid customers who signed up at sendgrid.com or twilio.com can add one new IP each month.
  1. Open the Twilio SendGrid Console.
  2. Go to Settings > IP Addresses.
  3. When adding the IP, select the EU region.
• Support-assisted
  Contact Twilio SendGrid support for more IPs or other help.

Assign your EU IP to your EU subuser and that you're using the EU API endpoint.

Data Residency will require you to create a new EU assigned subuser. We know migration is important and have a guide to walk you through this process. Subuser Migration from Global to EU Subusers

Yes, but you'll need to configure and authenticate the domain separately for each region by selecting "Make domain EU-pinned" in the advanced setting. That means setting up SPF, DKIM, and domain verification in both environments.

The EU-specific API endpoint is https://eu.api.sendgrid.com. Using this is critical to data residency.

No. EU subusers need EU-provisioned IPs. To prevent errors from improper configuration, you can't link global IPs to EU subusers.

No. Data Residency requires a dedicated EU IP. Shared IP customers will need to upgrade a Pro or Premier package to use this feature.

No. Sending through a parent or global subuser, even with an EU IP address, defaults to the global endpoint (api.sendgrid.com). This routes data outside the EU. You need an EU subuser using the EU API endpoint for true EU data residency.

Not at all. The EU infrastructure is built to deliver the same speed and reliability as our global systems. You can expect the same level of performance, just with the added bonus of data residency, specifically email recipients personal identifiable information and email event data.

If your email send fails due to incorrect EU configuration, expect to receive the following API error:

1
{
2
    "errors": [
3
        {
4
            "message": "User is not authorized to send mail based on their regional attribute.",
5
            "field": null,
6
            "help": null
7
        }
8
    ]
9
}

Proper configuration requires using:

• An EU subuser
• The https://eu.api.sendgrid.com endpoint
• A dedicated IP provisioned within the EU.

All Twilio emails comply with the General Data Protection Regulation (GDPR) of the European Union regardless of data residency. Data residency helps meet customer specific PII privacy needs. Under the GDPR, the EU considers email event data such as opens, clicks, unsubscribes, and recipient email addresses as personal data. With Data residency, Twilio stores that data in the EU and processes it whenever possible within the EU. This data only leaves the EU upon your request or engineering issues require it.

To learn more about data processing and storage, see EU Data Processing Locations.

While Twilio strives for complete data residency, some instances can't meet this requirement. Twilio maintains data storage in the EU, but some processing instances, such as retrieval, may leave the region. Processing outside of the EU occurs when you request it for support requests or to use the Point Delete Service and Whitelist mail settings. The Twilio engineering team might need data access to process data to troubleshoot or improve the infrastructure.

Twilio includes the core functionality of EU Data Residency in its standard plans. Procuring additional dedicated EU IP addresses or other region-specific resources may incur additional charges. To learn more, see Twilio SendGrid pricing.​

Due to restrictions necessary to maintain data residency, EU-bound subusers can't use the following features:

• Marketing
• Activity
• Validation
• Geostats

Marketing Campaigns and related features aren't supported in the EU environment.

Only the EU can use Data Residency. Twilio is evaluating expanding to other regions based on demand and feasibility.​

For further assistance or inquiries about Data Residency, reach out to the Twilio SendGrid support team.

The SendGrid console provides no visual indicator that an EU-designated subuser links to a teammate. Account admins can confirm the region designation through account setup records or support.

Following GDPR ensures that you handle personal data with security and transparency. By requiring consent, communication, and opt-outs, it builds trust with recipients.

GDPR applies to any organization anywhere in the world that sends emails to recipients located within the EU. If your emails reach EU inboxes, GDPR applies to you.

PII includes more than names or passport numbers. It also includes email addresses, IPs, and device IDs. Basic email events like opens and clicks can involve PII.
