When the complaints quota exceeded, i.e. more than 0,1% of emails sent during the last 30 days are marked as spam, then mass email sendings are blocked. The quota is formed with both auto messages and manually sent messages. A pop-up with notification will be shown on every page of the admin panel. All auto messages and manually sent messages will be stopped.
The quota of 0,1% is lower than in other services. That is why you will have time to take actions and work on reputation of your email domain. When the reputation of an email domain is low because of high bounce rate and spam complaints, then email services block this domain and all emails. Email won't be delivered even to those who want to read emails from that domain. It may take a few weeks to unblock the email domain. What's more, it will affect the conversion rates greatly.
Please contact Dashly support in chat. They will help you to check the moments that might have affected the email campaigns blocking. You will have an opportunity to send emails via Dashly again.
There are no definite rules as the blocking is not done automatically. However, there are some recommendations you can follow and reduce the risk:
1. Think about the title.
Users often do not read the mail and mark it as spam.
2. Validate and segment the emails database.
Don't buy email databases - work only with those who are ready to get your emails. The title may depend on the segment. If the email is interesting to a certain segment at a particular period of time, they are likely to open the email (open rate increases) and go to your website.
3. Enable double opt-in.
Additional subscription confirmation will define loyal users who really need email from your company.
4. Check the campaigns frequency.
Consider how many times a lead will receive emails from your domain within a month - the number should worth it.
