Terms of service
Last updated 10 November 2026
These terms are an agreement between you and WiseSender ("we", "us") for use of wisesender.com, the dashboard, the APIs and the SMTP relay (together, the "Service"). By creating an account or using the Service you accept them. If you use the Service for a company, you confirm you may accept these terms on its behalf.
1. Your account
You must give a real email address and keep your password and API keys secret. You are responsible for everything done with your account and keys. Tell us straight away at [email protected] if you think someone else has access. You must be at least 18 years old.
2. What the Service does
WiseSender checks whether email addresses can receive mail, lets you build contact lists and send campaigns through a mailbox you connect, and sends transactional email from domains you verify. Verification results are an informed assessment from public DNS and the answers of receiving mail servers. They are not a guarantee that a message will be delivered or read.
3. Credits and payment
- Verification credits pay for checks; one credit checks one address. Email credits pay for transactional sends; one credit sends one email to one recipient.
- Paid credits do not expire while your account is open. Free daily credits reset each day at 00:00 UTC and cannot be carried over.
- Prices are shown in US dollars and may be charged in Bangladeshi taka at the rate shown at checkout. Payments are processed by our payment providers; we do not store card details.
- Promotional credits and codes have no cash value.
- Refunds follow the refund policy.
4. Acceptable use
You must follow the acceptable use policy. In short: only email people who gave you permission, never send spam, phishing or malware, and never use the Service to break the law. We may pause sending, suspend or close an account that breaks these rules, and we do not refund credits on accounts closed for abuse.
5. Sending limits
New accounts start with conservative daily sending limits that we raise as your bounce and complaint rates prove healthy. We may pause sending automatically when bounce or complaint rates pass safe thresholds, to protect the shared infrastructure.
6. Your data
You keep all rights to the lists, contacts and content you upload. You give us permission to process them only to provide the Service. You confirm you have the right to upload and process that data. How we handle personal data is described in the privacy policy.
7. Availability and changes
We work to keep the Service available but do not promise it will be uninterrupted or error-free. We may change or improve features. If we make a change that materially reduces what you paid for, you may ask for a refund of unused paid credits.
8. Liability
The Service is provided "as is". To the extent the law allows, we are not liable for indirect or consequential losses, lost profits or lost data, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim.
9. Ending the agreement
You can stop using the Service and ask us to delete your account at any time. We may end or suspend your access if you break these terms. Sections 6, 8 and 10 continue after the agreement ends.
10. Law and disputes
These terms are governed by the laws of Bangladesh. We will first try to settle any dispute by talking to you directly; if that fails, the courts of Bangladesh have jurisdiction.
