How InboxImpacts Works


InboxImpacts Features
Complete Setup
InboxImpacts not only sells you inboxes but also runs the entire campaign. From purchasing a domain and setting up Google inboxes to writing email copy, A/B testing, building lead lists, and integrating with Sequencer, it covers all of these in its plans.
Domain Purchase
InboxImpacts purchases domains on your behalf. Each domain can include up to 5 Google inboxes, and the sending limit is 7,500 emails/month.
In-built Warmup
InboxImpacts runs warmup for you. But the warmup methodology is not defined.
Pre-Written Email Content
No inbox provider offers email content writing service. InboxImpacts writes email copies for you. You’ve 4 follow-ups per campaign, where you can A/B test with Spintax variation.
Pros
Fully Functional Setup
InboxImpacts sets up everything for you – inboxes, domains, copy, follow-ups, the lead list, and sending.
Transparent, Cancellable Billing
Plans are billed monthly with no annual lock-in period. However, if you decide to keep the domains and inboxes after a refund, you’ll have to pay extra for those.
Bundled Lead Data and Copy
Each InboxImpacts plan includes written email content and a large USA B2B lead database. That reduces the dependency on external tools/parties to generate email copy and lead list.
Cons
No Deliverability Monitoring or Burn Detection
There’s no domain-burn monitoring, inbox-placement test, or burn-detection system. This means that if your domain gets flagged, it will reduce the reply rate, ultimately affecting the outcome.
India-Origin Google Inboxes
InboxImpacts offers Google inboxes originating from India. Historically, Indian-origin Google inboxes have lower deliverability success than US-origin Google inboxes.
Unsafe Daily Sending Volume
The daily sending limit mentioned in the basic plan is 7,500 emails/month across 5 inboxes. This is 50 emails per day per inbox. This number is way above the commonly cited safe Google band of 15 to 25 emails per inbox per day.
Higher sending volume can burn the domains faster. And if not monitored, it compounds and impacts the domain.
No Warmup Methodology
Warmup is run for you as part of the service, but no pool, method, or metric is published. So there’s no way to tell the credibility of the warmup. Without a warm-up, sending 50 emails per inbox daily is risky. The chances of your emails hitting the spam folder or increasing bounce rates increase with pre-warmed-up inboxes.
No Control Access
You can’t gain control of your Google inboxes or campaign on InboxImpacts. Their managed model restricts client interaction. You can’t change the email frequency or pause sending from a burnt inbox.

InboxImpacts offers three plans, billed monthly.
| Plans | Google Inboxes | Price | Domains |
