Zapmail offers pre-warmed Google Workspace and Microsoft 365 mailboxes at $2.99-3.50 per inbox with 10-minute setup. MailDeck provides three infrastructure types under one provider - Microsoft 365, Google Workspace, and Private SMTP - starting at $0.30/inbox. The key difference: MailDeck adds SMTP as a third layer and runs at a significantly lower price at scale.

MailDeck manages 4.35M+ inboxes across Microsoft 365, Google Workspace, and SMTP for 1,631+ clients, sending 65M+ emails per day with a 98% inbox placement rate. Based on Q2 2026 MailDeck platform data.

Zapmail pricing verified on [zapmail.ai](https://zapmail.ai/#pricing) as of May 2026.

This comparison covers pricing at every scale, infrastructure differences, and where each provider makes more sense. For a broader view, see our [pricing analysis of 11 cold email providers](https://maildeck.co/blog/cold-email-infrastructure-cost-2026).

## Short Answer: The Best Zapmail Alternatives for Cold Email

The main Zapmail alternatives for cold email are MailDeck, Primeforge, Maildoso, Mailforge, Inframail and Aerosend. They differ on three things: which infrastructure they sell (Microsoft 365, Google Workspace or SMTP), whose IPs you send from, and what an inbox costs.

- MailDeck is the only one of the six that sells all three infrastructure types - Microsoft 365, Google Workspace and Private SMTP - under one provider, from $0.30/inbox with every price published.

- Primeforge is the closest like-for-like swap: Google Workspace and Microsoft 365 mailboxes, like Zapmail, at $4.50/slot on annual billing, with API access.

- Maildoso sells Google Workspace and SMTP at roughly $1.90-2.25/inbox on shared IP pools, with a $99/month dedicated IP add-on.

- Mailforge sells SMTP-only mailboxes on a shared IP pool at $3/mailbox (annual billing).

- Inframail sells private SMTP inside the Salesforge ecosystem and does not publish pricing.

- Aerosend sells private SMTP on aged dedicated IPs in batches of 30 mailboxes, with warmup included.

If you left Zapmail because of per-inbox cost, MailDeck Outlook at $0.30-0.40/inbox is the biggest price drop on the list. If you want the same Google + Microsoft product from a different vendor, Primeforge is the closest match. If you want SMTP, which Zapmail does not sell, compare MailDeck Private SMTP, Inframail, Aerosend and Mailforge on IP model first.

## Zapmail Alternatives Compared

| Provider | Infrastructure | Lowest published cost per inbox | IP model | Entry point | Best fit |
|---|---|---|---|---|---|
| MailDeck | Microsoft 365 + Google Workspace + SMTP | $0.30 (Outlook Normal) | Official Microsoft/Google pools + dedicated SMTP IP per client | $28/mo (10 Google inboxes) or $60/mo (200 Outlook inboxes) | Teams running 50+ inboxes, or a mixed Outlook/Google/SMTP stack |
| Zapmail | Google Workspace + Microsoft 365 | $2.99 (Pro tier additional) | Google and Microsoft IPs (US/EU) | $39/mo (10 mailboxes) | Small teams that need pre-warmed mailboxes in 10 minutes |
| Primeforge | Google Workspace + Microsoft 365 | $4.50/slot (annual billing) | US IP addresses | 10 mailbox slots | Teams that want Zapmail's product mix plus API access |
| Maildoso | Google Workspace + SMTP | ~$1.90-2.25 | Shared IP pools ($99/mo dedicated IP add-on) | ~$50/mo | Budget SMTP with built-in domain registration |
| Mailforge | SMTP only | $3.00 (annual billing) | Shared IP pool | 10 mailbox slots ($30/mo) | Salesforge users who want SMTP in 5 minutes |
| Inframail | Private SMTP only | Not published (sales call) | Private SMTP with IP rotation | Not published | Salesforge ecosystem teams willing to get a custom quote |
| Aerosend | Private SMTP only | $3.50-4.00 per mailbox (30-mailbox batches) | Aged, pre-warmed dedicated IPs | $120/mo (30 mailboxes) | Teams that want managed SMTP with warmup included |

## Which Zapmail Alternative Fits Your Team

| If your reason for leaving Zapmail is... | Look at | Why |
|---|---|---|
| Cost per inbox at 100+ inboxes | MailDeck Outlook | $0.30-0.40/inbox in 100-inbox tenants versus $2.99-3.50 at Zapmail. 1,000 inboxes cost $300/mo versus $2,999/mo. |
| You need SMTP as a volume buffer | MailDeck Private SMTP, Aerosend, Inframail, Mailforge | Zapmail does not list a dedicated SMTP product. MailDeck SMTP is $0.95/inbox with a dedicated IP per client. |
| Managing one domain per workspace | MailDeck Outlook | 100 inboxes per Outlook tenant, so 1,000 inboxes need 10 domains instead of 1,000. |
| You want the same Google + Microsoft product elsewhere | Primeforge | Same two infrastructure types, slot-based pricing, API access. |
| You want all infrastructure with one vendor | MailDeck | Microsoft 365, Google Workspace and SMTP on one account, so you can run a [diversified stack](https://maildeck.co/blog/cold-email-infrastructure-diversification). |
| You must send today, from 10 inboxes | Stay on Zapmail | Pre-warmed Google and Microsoft mailboxes in 10 minutes is hard to beat at that size. |

Before switching, run the same checks on any provider: whose IPs you send from, how many inboxes sit on each domain, how many cold sends per inbox per day the provider supports, and whether prices are published. Our guide on [how to choose a cold email inbox provider](https://maildeck.co/blog/cold-email-inbox-provider-how-to-choose) walks through each check.

### Head-to-Head at Scale

| Scale | Zapmail (Pro plan) | MailDeck (Outlook Normal) | Annual savings |
|---|---|---|---|
| 100 inboxes | $299/mo | $30/mo (1 tenant)* | $3,228/yr |
| 200 inboxes | $599/mo | $60/mo (2 tenants) | $6,468/yr |
| 500 inboxes | $1,499/mo | $150/mo (5 tenants) | $16,188/yr |

## Infrastructure Differences

### MailDeck: Three Provider Types with Official IPs

MailDeck provisions dedicated Microsoft 365 tenants, Google Workspace accounts, and Private SMTP inboxes. Outlook tenants route through official Microsoft Azure IP pools. Google Workspace uses official Google IP pools. SMTP uses dedicated IPs per client. Zero shared IP risk across any product.

Each Outlook tenant includes 100 inboxes with automated SPF, DKIM, and DMARC configuration. Teams can diversify sending across all three infrastructure types using the recommended [50/30/20 diversification ratio](https://maildeck.co/blog/cold-email-infrastructure-diversification) for optimal deliverability and risk management.

### Zapmail: Pre-Warmed Google and Microsoft

Zapmail provides pre-warmed Google Workspace and Microsoft 365 mailboxes with 10-minute setup and US/EU IP addresses. They use domain isolation (one domain per workspace) and offer tools like Domain Genie for domain management. Each plan includes placement test credits for monitoring inbox placement.

Pre-warmed delivery is a legitimate advantage for teams that need to send immediately. Zapmail does not offer a dedicated SMTP product.

## Where MailDeck Falls Short

Two objective disadvantages compared to Zapmail as an inbox provider.

Setup speed. Zapmail delivers pre-warmed mailboxes in 10 minutes. MailDeck Outlook tenants take 2-3 days. MailDeck Google Workspace provisions instantly, but requires 2-3 weeks of warmup before full cold sending volume. MailDeck Pre-Warmed Outlook is ready immediately, but provisioning still takes 2-3 days. For teams that need inboxes sending today, Zapmail is faster.

Pre-warmed across all products. Zapmail's mailboxes arrive pre-warmed across both Google and Microsoft. MailDeck offers Pre-Warmed Outlook (ready immediately), but Google Workspace requires 2-3 weeks and SMTP requires 3-4 weeks of warmup. For a guide on warmup protocols, see our [warmup guide](https://maildeck.co/blog/cold-email-warm-up-what-actually-works-2026).

## Where MailDeck Wins

Dramatically lower cost at scale. MailDeck Outlook Normal costs $0.30/inbox versus Zapmail's $2.99-3.50/inbox. At 500 inboxes, MailDeck costs $150/month versus Zapmail's $1,499/month. At 1,000 inboxes, the annual savings reach $32,388.

Three infrastructure types. Zapmail covers Google and Microsoft. MailDeck adds Private SMTP with dedicated IPs per client as a volume buffer layer. Running a diversified stack across Outlook, Google, and SMTP reduces risk and lets teams absorb volume spikes without burning premium inboxes.

100 inboxes per Outlook tenant. Each MailDeck Outlook tenant includes 100 inboxes per domain. Zapmail uses domain isolation with one domain per workspace. At 1,000 inboxes, MailDeck needs 10 Outlook domains versus 1,000 Zapmail domains. The management difference at scale is substantial.

Official provider IP pools. MailDeck Outlook inboxes route through official Microsoft IP pools, whitelisted by default on corporate mail servers. Google Workspace uses official Google IP pools. MailDeck maintains 98% inbox placement across 4.35M+ managed inboxes based on Q2 2026 platform data.

Transparent scaling. MailDeck pricing is flat per tenant or per inbox. No tiered plans with included-mailbox bundles and per-additional-mailbox surcharges. To plan your infrastructure needs, see our [inbox calculator](https://maildeck.co/blog/how-many-inboxes-cold-email).
