Simpletexting email verification with BillionVerify
SimpleTexting is an SMS and text message marketing platform used to engage contacts through bulk texts, drip campaigns, and two-way conversations. BillionVerify adds an email verification layer so any email addresses collected alongside phone numbers are validated before being used in cross-channel outreach.
Why verify before the send
Many SMS campaigns collect email addresses during opt-in flows for follow-up sequences. Unverified emails lead to bounces that damage your sending domain and inflate your list with dead contacts. BillionVerify removes invalid, disposable, and role-based addresses so your cross-channel data stays clean from the start.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Simpletexting sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

Ready-to-use workflows that verify emails before Simpletexting sends.
How it works
- 1
Connect BillionVerify to SimpleTexting via the n8n community node, Integrately, or the REST API.
- 2
Trigger verification when a new contact is created, a list is imported, or on a scheduled batch cadence.
- 3
BillionVerify evaluates each email address for format errors, DNS validity, disposable domains, role accounts, and catch-all configurations.
- 4
Invalid or risky addresses are flagged and can be automatically removed or moved to a suppression segment.
- 5
Only verified email addresses remain active in SimpleTexting, keeping your cross-channel campaigns healthy.
When to use this
Validate emails gathered in SMS opt-in forms
When contacts provide an email during SMS keyword opt-ins or web sign-up forms, BillionVerify instantly checks each address before it is stored. This prevents bad data from entering your SimpleTexting contact database.
Clean imported contact lists before email follow-ups
Before uploading a list to SimpleTexting that includes email fields, run it through BillionVerify to remove undeliverable addresses. Cleaner imports mean fewer bounces and better deliverability on any follow-up email campaigns.
Maintain list hygiene across multi-channel workflows
Automate periodic verification of email addresses stored in SimpleTexting contacts so stale or abandoned addresses are identified and suppressed before your next campaign cycle.
FAQ
Why would an SMS platform need email verification?
Many SMS workflows collect email addresses for follow-up sequences or CRM sync. Verifying those emails prevents bounces and keeps your cross-channel contact data accurate and deliverable.
How quickly does BillionVerify return results?
Single-address checks via the REST API return results in under a second, making real-time verification at the point of opt-in fully practical for SimpleTexting workflows.
Can I verify a large imported list all at once?
Yes. BillionVerify supports bulk verification, so you can upload an entire contact list and receive cleaned results before importing into SimpleTexting.
