Frequently Asked Questions
How do you ensure my emails land in the inbox and not spam?
To consistently land in the inbox, two things matter:
1. Start with high deliverability
2. Keep it that way over time
1. Starting with High Deliverability
We set your emails up for success by:
- Using a dedicated server with aged IPs, giving your domains a strong reputation from day one
- Warming up your domains with premium, human-like activity
2. Maintaining High Deliverability
Here’s where we go the extra mile:
- Rotate IPs before they get flagged- Alert you when domains need to be replaced
- Control sending speed to avoid spam filters
- Dynamically adjust warmup volume based on performance
- Keep burner accounts running in the background to protect your core sending reputation
How does your Dynamic Deliverability Engine work?
Our engine constantly monitors and adapts your sending setup to keep your emails landing in the inbox.
Here’s how:
- Inbox Placement Testing
We run weekly inbox placement tests on your domains. If anything starts landing in spam, you’ll get an alert right away.
- Domain-Level Performance Monitoring
We compare how each of your domains is performing. If one falls behind, we adjust its warmup settings automatically to help it recover, and we notify you too.
- IP Health Monitoring
If we detect a drop in IP performance, we proactively rotate your IP before it affects your deliverability.
- Bounce Rate Analysis
We watch for bounce spikes, especially domain-rejected bounces, and take action to prevent long-term reputation damage.
How many domains can I connect?
As many as you would like! With each domain, you get 3 inboxes.
Do you offer a free trial?
Unfortunately, we do not offer a free trial. Our setup, IPs, servers are very expensive so a free trial does not make sense.
