Book a 30-minute deliverability review
No slides. We look at your actual domains and mailboxes on the call and tell you what to fix first.
- A live check of your domains: DNS records, blacklist status, bounces and domain score.
- A read on your inbox placement: how much lands in the inbox and how much goes to spam.
- A written warm-up plan for your mailboxes, yours to keep either way.
Tuesday, 10:00 AM IST
Pick “Deliverability review” in the form and a specific IST slot will be proposed by email, no external scheduler.
Support, answered
The questions we get most before someone writes in.
Support requests get a first reply within 4 hours during IST support hours. Sales and deliverability reviews are answered the same business day, and everything else within 24 hours.
No. You can connect domains you already own, buy mailboxes through Infrabox, or connect Google Workspace, Microsoft Outlook, Microsoft Azure and custom mailboxes later. We can help you plan it first.
Up to 3 mailboxes per domain on the standard setup. Plans of $1,000 or above can create up to 5 mailboxes per domain.
Plan on 2 to 3 weeks at minimum, longer if you want more reputation behind each mailbox. Warm-up is $3 per mailbox per month, and works with mailboxes you connect as well as ones you buy.
InfraGuard for domain score, blacklist, DNS, bounce and IP monitoring; Email Validate for checking addresses before a campaign; and Inbox Placement for seeing how much of your email reaches the inbox versus spam.
Yes. Select "Support" as the reason and it goes directly to the support team, not an account rep.
