CSV bulk sending
What you get with CSV bulk sending
Send one message to a list without a campaign or any code. Upload a CSV, clean it in your browser, see the price, and send up to 250 recipients in a single reserved batch.
Read in your browser
Your file is parsed locally. Choose the phone, WhatsApp or email column and the rows are checked instantly.
Duplicates merged
Repeated numbers are merged, local numbers are completed with your country code, and anything invalid is set aside.
One price for the batch
See the full cost for every recipient before you send, including SMS segments.
All or nothing
The whole batch is reserved in one step. If the balance is short, nothing is sent.
Also in the API
Quote and send the same batch from your server with a recipients array instead of a single address.
Tracked per recipient
Every recipient gets its own message ID and status in the delivery logs.

CSV bulk sending setup
How it works
Prepare the list
Include a header row and a phone or email column. Use international phone numbers for SMS and WhatsApp.
Review imported rows
Choose the recipient column and remove invalid or duplicate recipients. Confirm permission for every recipient you keep.
Quote the batch
Review the selected channel, sender, template where required, and price. Direct bulk requests support up to 250 unique recipients per batch.
Queue and monitor
The API reserves the full quote and queues the batch in one transaction. Keep the returned message IDs to track each send.

Questions about CSV bulk sending
Can I send a batch through the API?
Use POST /api/v1/bulk/quotes and POST /api/v1/bulk/messages. Replace the direct to field with a recipients array.
What if a row becomes ineligible?
The API can reject the batch when a recipient, quote, or balance changes. Resolve the problem and obtain a fresh quote before submitting a new request.
What if my list has more than 250 people?
Split it into batches of 250, or use a campaign for larger audiences with a spending cap.
Does my file get uploaded?
The file is read in your browser. Only the recipients you choose to send to are submitted with the batch.
What if a row becomes ineligible before sending?
The batch is rejected so nothing partial goes out. Fix the row, request a fresh quote and submit again.
