Contact Send99 — Bulk SMS Support & Sales Team
Support channels and response times
Send99 support is available by email at [email protected], on WhatsApp at +44 7418 311837, and on Telegram. Support hours are 9:30 AM to 5:30 PM. Messages received outside those hours are handled on the next business day; urgent delivery incidents should include "urgent" in the subject and the message IDs affected.
To help us resolve an issue quickly, include your account name (never your password), the destination country, sender ID, approximate send time, message IDs, and the response or error you observed. Screenshots of delivery reports are useful, but avoid including full message content or personal data unless it is necessary.
Sales, volume quotes, and onboarding
For a quote, tell us your destination countries, estimated monthly volume, peak messages per second, sender type, and whether you need one-way or two-way traffic. If you are migrating from another provider, share the routes and features you rely on so we can confirm compatibility before you commit. See pricing for how per-message rates and volume tiers work.
Onboarding can include test credits, API or SMPP credentials, sender registration guidance, and a production checklist. Regulated use cases may need additional review. We will tell you what is required for your destinations rather than promising a one-size-fits-all setup.
Technical and integration help
Our team can help with the HTTP SMS API, SMPP binds, delivery-report handling, and inbound-message routing. Start with the API documentation and include the endpoint, request parameters (with credentials removed), response body, and timestamp in your support request.
For production incidents, tell us whether the issue affects all destinations or one route, whether new sends or only reports are failing, and what changed recently. That information shortens the path to a fix and helps us distinguish an integration bug from a carrier or registration issue.
Compliance and account questions
We can explain the sender-registration and consent requirements for the countries you target, but we cannot provide legal advice. Your business remains responsible for its opt-in records, message content, and local registrations. Our country pages summarise the main rules, and our terms of service set out acceptable use.
For billing, refunds, or data-protection requests, include the account name and the relevant invoice or request details. See the refund policy and privacy policy for the formal process.
Frequently asked questions
How quickly does Send99 respond to support requests?
Support runs from 9:30 AM to 5:30 PM. Messages received during those hours are usually answered the same business day; messages outside them are handled on the next business day. Include your account name, destination, sender ID, message IDs, and the exact error to help us respond faster.
What contact channels are available?
You can reach us by email at [email protected], on WhatsApp at +44 7418 311837, and on Telegram. Use email for account, billing, and detailed technical requests, and WhatsApp or Telegram for quicker questions during support hours.
Can I get a custom quote?
Yes. Send your destination countries, monthly volume, peak messages per second, sender type, and whether you need two-way traffic. We will confirm routing, registration requirements, and pricing for your mix. See the pricing page for the general model.
Do you help with API and SMPP integration?
Yes. We can help with credentials, endpoint behaviour, delivery reports, inbound routing, and SMPP bind setup. Start with the API documentation, then send the endpoint, sanitised request and response, and timestamp if you need further help.
Do you provide compliance advice?
We explain sender-registration and consent requirements for your destinations, but we do not provide legal advice. Your business remains responsible for opt-in records, content, and local registrations. Our country pages and terms of service summarise the framework.
How do I report a delivery incident?
Include "urgent" in the subject, your account name (never the password), the affected destination and sender ID, approximate send time, message IDs, and whether new sends, reports, or both are failing. Tell us what changed recently so we can separate an integration issue from a carrier or registration problem.
