Resolving SendGrid Email Errors in Bubble
Email errors when integrating SendGrid with Bubble apps often occur due to exceeding quotas or unresolved sender identity verification issues. This article summarizes common errors, their causes, and how to resolve them.
Managing SendGrid Quotas and Credits
Many errors stem from reaching email-sending limits. The following demonstrates common situations and resolutions:
Error: 'Maximum credits exceeded'
Cause: This error appears when you exceed the number of emails allowed by your SendGrid plan. Each email sent consumes one credit. For example, SendGrid Free plan users are limited to one email per day. Credits renew monthly.
Resolution:
Wait for the monthly quota to reset on your account.
Upgrade to a higher SendGrid plan with more email credits to remove limitations.
Contact SendGrid support to review your quota.
Error: 'SendGrid allowance has been exceeded'
Cause: This message is specific to Bubble’s default/shared SendGrid email integration. It imposes a daily quota of 20 emails, each allowing up to 50 recipients. These limits apply unless you connect to a personal SendGrid account.
Resolution: To avoid this limitation, configure your application to use a custom SendGrid API key. Follow the guidelines below for setup.
Custom SendGrid API Key Setup in Bubble:
Create your own SendGrid account and log in.
Generate an API key under the "API Key" section of your SendGrid account.
Navigate to Settings > Domain/Email in Bubble.
Enter the generated API key into the "SendGrid API Key" field.
Click Verify SendGrid Key to complete the integration.
Resolving "From" Address Verification Errors
SendGrid requires all sender email addresses (i.e., the "From" address) to be verified in your account. Unverified addresses will prompt errors.
Error: 'The from address does not match a verified Sender Identity'
Cause: The specified sender address has not been verified in SendGrid. This is mandatory, even if your domain is already authenticated.
Resolution: For resolution:
Log in to your SendGrid account.
Verify the specific sender email or authenticate the entire domain.
If creating new addresses (e.g., admin@your_domain.com), ensure you have access to receive the sender identity confirmation email.
In Bubble, ensure the verified email is set under your email workflow.
Tips for Domain-Wide Authentication:
Instead of verifying individual addresses, authenticate your domain through SendGrid. With domain authentication:
You can use any email in the verified domain without individual verification requirements.
Follow SendGrid’s Sender Identity Documentation for steps.
Common Troubleshooting Questions
Why do I encounter "Maximum credits exceeded" when validating a SendGrid API key in Bubble?
Cause: You’re either using Bubble’s default SendGrid setup (with limits) or your own SendGrid account, but your plan’s quota has been surpassed.
Resolution:
Upgrade to a higher-tier SendGrid plan.
Validate email credits or API status under SendGrid settings.
By understanding these common errors and implementing the solutions provided, you can improve your Bubble app’s email delivery performance and prevent common email limits or identity issues.
