About ScaledMail
ScaledMail has a very cool feature where you can select what % of emails will be sent from what inbox type. For example, if you want to send cold emails to 5,000 leads, you can mix and match between Google, Azure, and SMTP inboxes.
ScaledMail automatically sets up the domains and configures SPF, DKIM, and DMARC.
Since ScaledMail doesn’t have an in-built warmup, you can warmup through your sequencer.
How ScaledMail Works
ScaledMail Features
Multi-Inbox Provider
ScaledMail offers Google, Azure, and SMTP inboxes. The Google inboxes are sourced from Indian resellers. Only Indian Google inboxes are available at $3.50/inbox. For US Google inboxes, you have to pay atleast $8/inbox. Historically, compared to Google inboxes originating from US, Indian google inboxes have lower deliverability success.
Custom Inbox Selection
You can control the inbox composition and spread the sending across providers. It is the most-stated differentiator across competitor reviews.
Automatic Setup
ScaledMail sets up the domains for you. All you have to do is select the volume and a provider split. The ScaledMail team connects your domains, configures SPF, DKIM, and DMARC, and creates the inboxes. Inbox creation usually takes 2 to 4 business days.
Deliverability Monitoring
ScaledMail claims deliverability monitoring, but there is no published methodology. The reporting is an add-on and costs around $2/inbox.
IP rotation
ScaledMail claims IP rotation on Azure inboxes, roughly every 15 days. That rotation is unverified, and Azure IPs sit in an opaque Microsoft pool that cannot be monitored or controlled.
Pros
Multi-Provider Mix
ScaledMail lets you run Google, Azure, and SMTP inboxes side by side in one package, with a split you set. Instead of betting everything on one provider, you spread your sending across three, so if one provider type gets flagged, the rest of your campaign keeps moving.
Genuine Azure Tenant Isolation
ScaledMail provides each client with an isolated Azure tenant, which is the one genuine strength of the Azure model. The IPs themselves are Microsoft’s opaque pool, so they cannot be monitored or controlled. ScaledMail claims to rotate IPs every 15 days to refresh inbox reputation. But Azure’s deliverability rate has received mixed reviews. Therefore, evaluate your options properly before committing.
Automated DNS Setup
ScaledMail connects your domain and registers SPF, DKIM, and DMARC.
Cons
Warmup Is Not Included
Unlike Aerosend, ScaledMail does not have a built-in warmup. You have to run the warmup through your sequencer. If you are not tracking warmup performance actively, this can significantly impact deliverability.
No Analytics
There’s no way to monitor your inboxes as ScaledMail doesn’t provide analytics dashboard. Which means you can’t track inbox placement, bounce rate, or IP health.
Order Delivery Takes 2-4 Business Days
The order inbox fulfillment takes time. The ScaledMail team takes 2 to 4 business days to set up the inboxes and DNS.
Deliverability Reporting for $2/Inbox
You can include deliverability monitoring with your plan by paying $2/inbox for Google and SMTP, or $5/domain for Azure.

Aerosend: Best Alternative to ScaledMail
ScaledMail offers Google, Azure, and SMTP inboxes. It handles DNS and inbox setup for you.
But the inboxes don’t come with premium warmup; you need a sequencer to warmup. The daily send limits sit inside the safe band, so you need multiple inboxes for higher volumes. Reporting is thin: there is a self-serve dashboard for provisioning, but no deliverability analytics.
If you want inboxes with deliverability rates, premium warmup, and inbox reputation management, you may prefer an alternative that offers a complete cold email setup.
Aerosend offers a complete cold email infrastructure, which provides –
- Geo-mapped SMTP inboxes (US IPs for US clients, EU IPs for EU clients)
- Dedicated IP for your domains (10 domains/IP)
- Complimentary Premium Warmup using Warmupinbox ($40/inbox)
- Biweekly inbox placement tests

ScaledMail Support
Support is available via both Slack and email. You can email ScaledMail support at support {at} scaledmail {dot} com.
At core all inboxes are the same; what distinguishes ScaledMail is the intent to help in every situation. Switching domains, editing users, deliverability analysis, volume up or down, reconnections, all within 24 hours.

The Verdict
After reviewing ScaledMail inbox quality and features, here’s what we conclude:
- ScaledMail provides a multi-inbox setup: Google and Azure Reseller + SMTP.
- DNS setup included
The drawbacks: No built-in warmup; 25/day on Google and 10/day on Azure and SMTP. Require multiple inboxes for scaling. Thin dashboard + reporting.
It is best for agencies that can self-manage warmup and placement while ScaledMail handles provisioning.
If you want better deliverability, a higher reply rate, geo-mapped inboxes, and a dedicated IP, Aerosend is the better fit. Aerosend manages your deliverability for you and offers the best solution for your cold email campaigns.
