Q: Do you plan to implement the below features?
Anti-spam test:
Before you submit your campaign, INBOX will test it to make sure it does not end up in the spam box. That way, your message will arrive safely in your readers' inboxes and increase your chances of a successful campaign.
Predictive delivery:
INBOX analyzes all contacts to find the best time to submit your campaign. The software detects the exact day and time when your emails get the most likely opened for each contact in your list. Thus, your messages will be delivered at the best time.

May 14, 2024A: Hello Soyoo,
1) We already have "Warm-up" process for our new users, it's called "Phishing Control". This process is applied in your first 4-5 campaigns. Emails are sent slower in this process, but with an increased deliverability rate.
We do everything to increase spam rates but it's also the nature of email marketing because we don't decide if it's spam or not, service providers are deciding. There's so many factors that have affect on spam, for example the content of your emails, if there's a video or GIF, even the title of your emails. But if you reach out to our support and ask them to analyze your newsletter, they'll help you about it.
2) We're planning this kind of a feature actually. That would be great to have this, i agree with you. Our DevOps team will evaluate this feature in the future. You can also write this to our roadmap for them to see.
