Zoho Campaigns has a broad spectrum of users, ranging from new businesses to seasoned players. We are committed to offering a safe and secure email experience for all our users, so our anti-spam team validates all signup requests we receive. If we find a signup request to be suspicious, we will suspend the account creation process. We keep a constant vigil over our users to ensure that they follow hygienic email sending practices and comply with our terms and other data protection laws.
Suspension of account – An infographic.
The global landscape of email compliance now extends well beyond GDPR and CAN-SPAM. Depending on where your subscribers are located, you may also be required to comply with CASL (Canada), CCPA/CPRA (California), UK GDPR, Australia's Spam Act, and a growing number of US state privacy laws — eight of which came into effect in 2025 alone. Compliance is determined by where your subscribers are located, not where your business is registered.
We suspend only the accounts of businesses that don't comply with our terms of use and data protection laws, as well as those who continue to follow unhygienic email sending practices even after we repeatedly request they correct their methods. Let's dive deep and learn more about the reasons we would suspend an account.
If the reputation of the sender domain is poor
When we review a campaign, we will validate all the attributes of the sender domain and the reputation it has with mailbox providers and anti-spam services. If the sender domain is found to be suspicious or if it faces deliverability and anti-spam issues, we will suspend the user's account.
A significant part of sender domain reputation is now tied directly to email authentication. Since February 2024, Google and Yahoo require bulk senders to authenticate with SPF and DKIM, and to publish a DMARC record for their sending domain. Microsoft extended the same requirements to its consumer email services in May 2025. A sender domain that lacks proper authentication records will receive a poor reputation score from major mailbox providers, regardless of sending behavior. We strongly recommend ensuring your sending domain has SPF, DKIM, and DMARC configured before sending campaigns.
When businesses sign up to use our services, they comply with our terms. This implies that they agree not to use our services to indulge in or promote prohibited businesses that are listed in our terms of use. If any of our users use our services to indulge in or promote these businesses, we will suspend the user's account. When the email content is spammy and suspicious
The content you offer hugely impacts the performance of your campaigns and your business. If the content is not relevant to your business, if it contains spammy phrases, or if it promotes businesses that are prohibited by us, we will suspend the account.
When a business receives anti-spam complaints
At Zoho Campaigns, we have tight integration with mailbox providers and anti-spam services. Whenever we receive feedback from them, we will follow their suggestions and take necessary corrective measures. Whenever we receive complaints about a user from anti-spam services or mailbox providers, we will suspend the user's account.
As a widely adopted industry benchmark, Google's bulk sender guidelines specify that senders should keep their spam complaint rate below 0.10% as a routine target, and must never allow the rate to reach 0.30% or above. These rates are measurable through Google Postmaster Tools. Monitoring your spam complaint rate regularly through this tool will help you identify and address issues well before they trigger a suspension.
When we identify a signup spammer
At Zoho Campaigns, we analyze the signup requests we receive and look for patterns that point to spam. If our anti-spam system finds an account creation process to be suspicious, we will suspend the account. Also, when we receive multiple signup requests originating from a single system (bot signups) or receive numerous signup requests from a single IP address, we will suspend the account.
To protect your own account from being caught up in automated bot activity, we strongly recommend using double opt-in for all your signup forms. Double opt-in requires new subscribers to confirm their email address before they are added to your list, which filters out invalid and bot-generated entries. Adding a CAPTCHA or reCAPTCHA to your signup forms provides a further layer of protection by blocking automated form submissions before they reach your list.
Having multiple accounts
Sometimes a user may create multiple accounts under a domain and try to send campaigns using those accounts. In such situations, we will block the accounts and ask the user to have one primary account and move all the other accounts under the primary account. The user can only send a campaign from the primary account.
Violation of our terms
When you sign up to use our services, you agree to comply with our terms of use, anti-spam policy, and the laws regulating the sending of commercial emails. If a user violates our terms, we will suspend their account.
To prevent your account from getting suspended, we urge you to implement hygienic email sending practices and comply with our terms of use. If your account is suspended and you wish to learn more about reinstating your account, you can write to our support team at support@zohocorp.com.
