ReplyDak vs Zapmail: price, features and which to pick
Updated 17 October 2026 · 6 min read
Short answer
ReplyDak is cheaper than Zapmail at every plan size ($35 vs $39 for 10 mailboxes, $87 vs $99 for 30, $269 vs $299 for 100), includes warmup, and bills in INR with a GST invoice. Zapmail is the better pick if you need Microsoft 365 mailboxes today, pre-warmed mailboxes, an API or built-in placement tests, none of which ReplyDak offers yet. Both sell real Google Workspace mailboxes on your own domains.

Where the price difference comes from
Both providers sell the same underlying product: a Google Workspace user account on a domain you own, with DNS records set so the mailbox can send authenticated mail. ReplyDak keeps the product narrower (Google mailboxes, warmup, domains, DNS) and passes the saving on, which works out to 10% less than Zapmail at each plan size. At 100 mailboxes the difference is $30 a month, or $360 a year.
In INR, ReplyDak charges ₹289, ₹249 and ₹225 per mailbox at 10, 30 and 100 mailboxes, with a GST invoice your finance team can claim input credit on. For Indian agencies and SaaS companies this removes currency conversion fees and the paperwork of a foreign-currency invoice.
When Zapmail is the better pick
- You need Microsoft 365 mailboxes now. Zapmail sells Microsoft at the same price as Google. ReplyDak's Microsoft 365 option is not live yet.
- You cannot wait three weeks for warmup. Zapmail offers pre-warmed mailboxes. New ReplyDak mailboxes start at about 2 emails a day and reach around 30 after roughly 21 days.
- You want to automate provisioning. Zapmail's API on the Pro plan lets you create mailboxes from your own software. ReplyDak has no API yet.
- You want placement tests in the same tool. Zapmail includes monthly test credits.
- You prefer a longer track record. Zapmail has been selling cold-email mailboxes for longer; ReplyDak opened to customers in October 2026.
When ReplyDak is the better pick
- You want Google Workspace mailboxes at a lower price and do not need an API.
- You are billed in India. INR pricing with a GST invoice is built in.
- You want warmup handled without a separate tool. It is included and adjusts itself if bounce or spam signals appear.
- You refer other teams. ReplyDak pays a 20% lifetime commission versus Zapmail's 10%.

Total cost example: 30 mailboxes for a year
A common agency or SDR setup is 30 mailboxes on about 12 domains (2–3 mailboxes each). Mailbox costs only, on monthly billing:
| ReplyDak | Zapmail | |
|---|---|---|
| Mailboxes per month | $87 | $99 |
| Mailboxes per year | $1,044 | $1,188 |
| 12 domains per year | $156 at $13 each (or bring your own) | Depends on TLD and offer |
| Warmup | Included | Included or pre-warmed option |
On mailboxes alone ReplyDak saves $144 a year at this size. Whether that matters depends on what you would use Zapmail's extras for: if pre-warmed mailboxes let you start a client campaign three weeks earlier, that can be worth more than the difference. Run your own numbers in the cost calculator.
What stays the same on either provider
- You still need separate sending domains, not your main company domain. See protect your main domain.
- You still need to keep each mailbox to a modest daily volume, about 30 cold emails. See cold email sending limits.
- You still need clean lists and an easy opt-out to meet Gmail, Yahoo and Microsoft bulk sender requirements.
