Process with email verification queue
Synchronous Batch Email Verification API verifies one or multiple emails in a batch, offline manner.
If you need to verify multiple email addresses in a batch, but you prefer synchronous integrations you can use our Synchronous Batch Email Verification API.
Each request adds new emails to batch processing queue, and returns response when result is known.
Speed
Default settings allow our customers to verify 100k email addresses per hour, however if your use case requires higher throughput, please let us know and we will be able to adjust your configuration.
Rate Limiting
The Batch Sync Email Verification API is limited to 100 requests per minute by default.
Batch size recommendation
Single request can hold up to 10,000 emails.
Special considerations
Requests should be sent sequentially with delay between requests of 5sec to 10min.
Results are kept up to 24h in Bouncer. After that delay email will be verified again and credits will be charged.
