Reach the right people. Skip the rest.
Validate contacts against the Indian DND registry and email deliverability before bulk calls, SMS and email — so teams stay compliant and stop wasting spend on unreachable numbers and bad addresses.
What DND & Communication Scrubbing delivers
Phone DND check
Check Indian mobiles against the TRAI Do-Not-Disturb registry via Exotel, and block or allow bulk voice and SMS by your rules.
Email deliverability
Verify addresses with Hunter.io and keep undeliverable emails out of bulk and automated email campaigns.
Status on every lead
Colour-coded DND and deliverability status with a last-checked date sit next to phone and email on the lead profile and listing.
Bulk verify contacts
Verify a saved search or up to 10,000 leads per run; results land on each lead and drive listing filters.
Verify at campaign launch
Choose 'proceed without verifying' or 'verify and proceed' — the latter checks at send and excludes DND-blocked numbers and invalid emails.
Rules you control
Set Allow/Block for DND and map Hunter results to Valid/Invalid; one-to-one calls, SMS and email are shown and warned, never blocked.
Spend provider credits once
Results are stored on the contact, reused across duplicates and clones, and re-checked only when you choose to re-verify.
Your provider accounts
Runs on your own Exotel and Hunter credentials — usage is billed on your accounts, not a Sell.Do wallet.
Device compatibility: Phone DND applies to Indian mobiles only (via Exotel); non-Indian numbers are marked unsupported and are not blocked on one-to-one calls or SMS. WhatsApp is out of scope for TRAI DND scrubbing — use WhatsApp opt-in. Requires active Exotel and Hunter accounts.
