An intuitive platform to clean and monitor your contact databases
Launch an HLR or EVR request directly from your dashboard, or integrate verification into your CRM via our API. Track the status of your numbers and emails at a glance.
HLR Lookup (phone numbers)
HLR (Home Location Register) queries mobile operator databases to confirm if a number is active, assigned, and reachable: number validity and status, operator and country of origin, and cost optimization for your SMS campaigns.
EVR (Email Verification)
EVR verifies the validity of an email address before you send your campaign, helping to limit bounces and protect your sender reputation: format checks, domain and DNS record verification, detection of risky addresses, and improved deliverability.
Why use the HLR & EVR verification solution from Octopush?
Benefit from a fast, reliable tool to make your SMS and email sends more dependable.
Cut your sending costs from your very next campaign
Every invalid number or inactive email address you send to costs you money with no return. On an unverified database of 10,000 contacts, that is potentially 2,000 to 3,000 sends going nowhere, billed at the same rate as reachable contacts. HLR Lookup and EVR identify those contacts before you send, cutting your cost per campaign directly without reducing your reach among genuinely active contacts. The higher your volume, the bigger the saving.
Protect your sender reputation over time
A high bounce rate does not just hurt one campaign: it degrades your sender score with mobile operators and email providers. Past a certain threshold, your messages are systematically filtered or routed to spam, however good your content. Verifying your databases regularly keeps your bounce rate below the critical threshold and protects the deliverability of all your future campaigns, not just the next one.
Integrated with your CRM or your technical pipeline
The HLR and EVR APIs plug straight into your CRM, your sending tool or your data processing pipeline. Trigger an automatic check on every new incoming contact, before each campaign or at regular intervals, with no manual action. Results are structured and immediately usable by your technical team. For large volumes, batch processing handles tens of thousands of contacts in minutes and returns a cleaned file ready to use.
SMS and email verified from one single interface
Most verification solutions cover only one channel. Octopush lets you verify phone numbers and email addresses in the same account, using the same credits, and gives you a consolidated view of your database's overall quality. A complete clean-up in a single operation, before launching your SMS and email campaigns in parallel, without multiplying tools, exports or subscriptions.
