Effective 8 October 2026 · Version 1.0

How newsletter writers, educators and organisations can send email to subscribers from Indo Mail: identity, consent, limits, domain authentication, list hygiene and audience growth.

1. What this page covers

Indo Mail is an email and productivity service run by INDO CHATS PRIVATE LIMITED from Kolkata, India. It is not a video or social platform. There is no live streaming, no virtual coins or gifts, no in-app shop and no creator payout programme. When we say "creators" on this page we mean the people and organisations who write to an audience by email: newsletter writers, teachers and coaching centres, community groups, NGOs, clubs and small businesses.

This Creator Center explains how to send email to subscribers from Indo Mail responsibly and with good delivery. It covers your sender identity, the consent and unsubscribe rules we expect you to follow, the daily sending limits, how to authenticate your own domain, how to keep your list clean, and the tools you can use to grow an audience. Anything that is not available today is clearly marked as planned.

2. Who this is for

You are a sender in the sense of this page if you write the same or similar message to many people who asked to hear from you. Typical examples are:

If you only write one-to-one email, most of this page will not apply to you. The general Acceptable Use rules still do.

3. Your sender identity

Recipients decide in a second whether to trust a message. A clear, stable identity helps them and helps receiving mail servers. We ask every sender to follow these rules:

4. Consent and unsubscribe rules

Email to a list must be wanted. India's Digital Personal Data Protection Act, 2023 and the Digital Personal Data Protection Rules, 2025 require a lawful basis for using a person's email address, and consent must be free, specific, informed and unambiguous. If you write to people outside India, laws such as CAN-SPAM in the United States, CASL in Canada and the GDPR or UK GDPR in Europe may also apply. Our rules are designed so that one sensible practice works everywhere:

Reports from recipients reach abuse@indoemail.in. Repeated complaints about a sender lead to a warning, a lower sending limit, suspension of sending, or closure of the account, depending on how serious and how frequent the problem is.

5. Daily sending limits

Every Indo Mail account may send up to 500 messages a day. Each recipient counts as one message, so a single email to 40 people in To, Cc and Bcc counts as 40. The counter resets every 24 hours. When you reach the limit, further sends are refused with a clear message until the window resets.

Account typeDaily limitHow to send more
Free (personal @indoemail.in)500 recipients a daySplit your list across days or move to Business on your own domain
Pro500 recipients a dayMove to Business on your own domain
Business (own domain)500 recipients a day per user to startAsk sales@indoemail.in for a reviewed higher limit for that domain
EnterpriseSet in the contractAgreed with our sales team after a sending review

Higher limits are only considered for Business and Enterprise domains with DKIM, SPF and DMARC in place, a low complaint rate and a clean bounce record. Mail to outside providers is relayed through Amazon Web Services' Simple Email Service; while our production access for that relay is still pending, large raises may be delayed. Do not create several accounts to get round the limit. That is treated as abuse.

6. Authenticate your own domain (DKIM, SPF, DMARC)

Receiving providers trust mail that proves where it came from. If you send from your own domain on a Business plan, set up all three records. The admin console shows the exact values for your domain and checks them live, so you can see which ones are correct.

RecordWhat it provesWhat to do
DKIMThe message was signed by Indo Mail for your domain and was not changed on the wayPublish the TXT record shown in your admin console. Each company domain gets its own DKIM key.
SPFIndo Mail's servers are allowed to send for your domainPublish one SPF TXT record that includes the value shown in the console. Keep only one SPF record per domain.
DMARCWhat receivers should do if DKIM and SPF fail, and where to send reportsStart with a monitoring policy, review reports for a few weeks, then move to quarantine and finally reject.
MXWhere replies to your domain should be deliveredPoint MX to mail.indoemail.in as shown in the console.

Free @indoemail.in addresses are already covered by Indo Mail's own DKIM, SPF and DMARC records; you do not need to do anything. Incoming mail to every Indo Mail user is checked against these same standards, and messages that fail go to Spam, which is another reason to set them up correctly.

7. List hygiene

A clean list delivers better, costs less effort and keeps you inside your limits. Good habits:

8. Business Profile

Business Profile gives you a simple public page on indoemail.in with your name, description, contact details, address and opening hours. It is a good place to point new readers to, and it shows recipients that a real person or organisation stands behind your emails.

Organisations on a paid plan can add the verified business badge for ₹1,499 a year plus GST. Verification checks that you are who you say you are, using your registration documents and your domain. The badge appears on your Business Profile.

9. Growing your audience with ads

You can advertise your newsletter, course or organisation through Indo Ads. All Indo Mail ads are contextual: they are matched to the placement, country, language and the words on the page, never to anyone's mail or personal data. Ads appear only to Free plan users and never inside messages.

See the Advertising Platform page for full rules, prohibited categories and billing.

10. Planned newsletter tools

We are designing tools for regular senders. They are planned and not part of the service today:

We will announce these features in the release notes when they go live. Until then, please do not describe them to your readers as available.

11. What we do not allow

We act on breaches under our Terms of Service and the Information Technology (Intermediary Guidelines and Digital Media Ethics Code) Rules, 2021.
