Send better email. Verify every address.

TheNotifier is one platform with two products and one login and billing system: Marketing & Email Campaigns, and an Email Verification API. Use either product, or both.

Marketing & Email Campaigns

Build your audience, design responsive emails in a drag-and-drop editor, schedule sends from your own authenticated domain and track opens, clicks and bounces.

Email Verification API

Verify addresses through a REST API with API keys, or upload a .csv or .xlsx file and download an Excel report with a status and reason for every address.

One platform

One login and one billing system across both products, with separate plans and limits for each.

Authenticated sending

Connect your own domain with SPF, DKIM, and DMARC for reliable email deliverability.

Plan-based limits

Each plan sets clear limits, and your plan steps up to the next tier when you reach your allowance.

Frequently asked questions

What is TheNotifier?

TheNotifier is one platform with two products. Marketing & Email Campaigns lets you manage subscribers, design emails in a drag-and-drop editor, schedule campaigns, authenticate your sending domain (SPF, DKIM, DMARC) and track results. The Email Verification API checks email addresses through a REST API or in bulk from CSV and Excel files. Both share one login and one billing system.

What is the Email Verification API?

It checks whether an email address is likely to be deliverable. Send an address to the API with your API key, or upload a .csv or .xlsx file in the portal, and each address gets a status (valid, risky, invalid or unknown) with a reason. Bulk jobs can be downloaded as an Excel report.

Do the two products share one account and one bill?

They run on the same platform with one login and one billing system, with payments handled by Paddle. Each product has its own plans and limits, and you choose a product when you sign up.

Is there a free plan?

Yes. The Free plan lets you try TheNotifier with no credit card required. Paid plans add higher subscriber and sending limits.

What happens when I reach my plan limit?

Your plan scales automatically. When you reach a limit such as subscribers or monthly emails, TheNotifier moves you to the next tier and charges your saved payment method, so campaigns, imports and verifications keep running. You are emailed about every change, and if a payment fails the work pauses and resumes once it succeeds.

Can I verify my email list before sending a campaign?

Yes. Email verification is built in: verify single addresses or bulk lists to catch invalid, risky, and disposable emails before you send, which protects your sender reputation and deliverability.

How does TheNotifier help my emails reach the inbox?

You authenticate your own sending domain with SPF, DKIM, and DMARC records, your lists are verified before sending, and every campaign is screened for phishing and policy violations. Together these keep your sender reputation healthy and improve inbox placement.

Can I upgrade or cancel my plan anytime?

Yes. You can upgrade from Settings at any time and it takes effect immediately. You can also cancel anytime; you keep access until the end of the billing period you already paid for.

How is payment handled?

Payments are processed securely by Paddle, our merchant of record. You can pay monthly, or yearly at a discounted rate.
