> SpamTitan and iBlockSpam compared on published prices, the 25-user minimum, spooling, quarantine digests and setup. Sourced, dated, with 10 and 50 user costs.

SpamTitan is a capable filter with sandboxing and a large product family. iBlockSpam is a simpler per-domain MX filter with no seat minimum. Here's how they compare on published facts, checked in October 2026, and which suits whom.

## The short answer

SpamTitan suits organizations of 25 or more users that want sandboxing and add-ons like archiving and encryption from one vendor. iBlockSpam suits small and growing businesses, and anyone with many mailboxes on one domain, that want a flat per-domain price, per-user quarantine digests, free DNS tools and a 30-day money-back guarantee.

Competitor details below were checked on TitanHQ's own pages in October 2026. Prices change; confirm them before you decide.

## Side by side

| | SpamTitan (TitanHQ) | iBlockSpam |
|---|---|---|
| Pricing model | Per user, per month, paid annually | Per domain, unlimited mailboxes (mailbox count, not message volume) |
| Published price | $2.40 per user/month | Protect $12 per domain/month billed annually ($144/year) or $15 month-to-month; Protect Plus $19 annually or $24 monthly. Beta pricing, USD, excluding tax |
| Minimum | 25 users | 1 domain |
| Trial or guarantee | 14-day trial (vendor says no payment card is needed) | No free trial; 30-day money-back guarantee on a domain's first annual subscription |
| Spooling if your server is down | Not stated for the cloud service on the pages we checked | Up to 5 days |
| Quarantine and digests | End-user quarantine reports | Personal quarantine for every user; digests hourly, daily, on a chosen weekday or custom; shared admin quarantine |
| Sandboxing | Yes | No |
| Archiving and encryption | Separate products (ArcTitan, EncryptTitan) | 30-day message history; no encryption product |
| Setup method | MX routing; TitanHQ says most users finish in "less than an hour" | MX change plus platform steps, with a guided setup wizard and rollback steps |
| Free tools | Not listed on the pages we checked | Email Health Check, MX, SPF, DKIM, DMARC, blacklist, PTR, MTA-STS, BIMI, header analyzer, SPF and DMARC generators |
| Contract notes | Annual billing on the published price | Annual or month-to-month; cancel any time in the billing portal, effective at period end |

## What it costs at 10 and 50 mailboxes

Assumptions: one domain, list prices only, USD, excluding tax, annual terms where offered. SpamTitan's price is the published $2.40 per user per month with its 25-user minimum. iBlockSpam's price is per domain, whatever the mailbox count.

| | 10 mailboxes | 50 mailboxes |
|---|---|---|
| SpamTitan (billed for at least 25 users) | 25 × $2.40 = **$60/month** ($720/year) | 50 × $2.40 = **$120/month** ($1,440/year) |
| iBlockSpam Protect, annual | **$12/month** ($144/year) | **$12/month** ($144/year) |
| iBlockSpam Protect Plus, annual | **$19/month** ($228/year) | **$19/month** ($228/year) |
| iBlockSpam Protect, month-to-month | $15/month | $15/month |

The comparison isn't like for like. SpamTitan's price includes sandboxing, which iBlockSpam doesn't offer. If you also need archiving, SpamTitan's ArcTitan adds $3.94 per user per month on TitanHQ's pricing page. If your business has several domains, each iBlockSpam domain is its own subscription; see [per-domain vs per-user pricing](https://iblockspam.com/compare/per-domain-vs-per-user-pricing) for multi-domain examples.

## When SpamTitan is the better choice

- **You want attachment sandboxing.** SpamTitan describes sandboxing that detonates suspicious attachments. iBlockSpam doesn't sandbox.
- **You want archiving, encryption or phishing add-ons from the same vendor.** TitanHQ sells ArcTitan, EncryptTitan and PhishTitan alongside SpamTitan, and bundles them.
- **You want to try before paying.** SpamTitan's 14-day trial needs no credit card, and TitanHQ offers an engineer review of your trial configuration.
- **You have 25 or more users anyway**, so the minimum doesn't change your bill, and you'd rather buy filtering, archiving and encryption from one vendor.

## When iBlockSpam is the better choice

- **You have fewer than 25 users.** There's no seat minimum, so a 10-person office pays for one domain, not 25 seats.
- **You have many mailboxes, shared mailboxes or aliases.** Pricing is per domain with unlimited mailboxes and unlimited domain aliases. Each domain includes 100,000 inbound messages a month.
- **You want users to manage their own held mail.** Every user gets a personal quarantine with [digests](https://iblockspam.com/features/quarantine-and-digests) as often as hourly.
- **You want to check your setup first, free.** Our [free tools](https://iblockspam.com/tools) don't ask for an email address, and the [Email Health Check](https://iblockspam.com/tools/email-health-check) shows your current MX, SPF, DKIM and DMARC.
- **You want prices you can read without a sales call.** Prices and limits are on the [pricing page](https://iblockspam.com/pricing), and a domain's first annual subscription has a 30-day money-back guarantee.
- **You want to know when your DNS changes.** [Domain monitoring](https://iblockspam.com/features/domain-monitoring) alerts you if MX, SPF or DMARC drift: weekly on Protect, daily on Plus.

## How to switch from SpamTitan

1. Run the [Email Health Check](https://iblockspam.com/tools/email-health-check) and save a copy of your current MX, SPF and DMARC records.
2. Export your allow and block lists from SpamTitan so you can recreate them.
3. Lower your MX record's TTL a day or two ahead.
4. Add your domain in iBlockSpam and follow the guided setup for your platform, such as the [Microsoft 365](https://iblockspam.com/platforms/microsoft-365) inbound connector with Enhanced Filtering for Connectors, or the [Google Workspace](https://iblockspam.com/platforms/google-workspace) inbound gateway.
5. Change MX, send test messages and check the headers with the [Email Header Analyzer](https://iblockspam.com/tools/email-header-analyzer).
6. Keep SpamTitan active until the old TTL has passed and it shows no new traffic for your domain, then cancel.

Our [migration plan](https://iblockspam.com/migrate) covers each step and the rollback. The vendor-neutral guide to [switching spam filter providers](https://iblockspam.com/blog/switch-spam-filter-provider) explains why mail goes missing during a cutover and how to avoid it.

## Frequently asked questions

### Does SpamTitan's 25-user minimum apply to a 10-person office?

TitanHQ's pricing data, checked in October 2026, lists SpamTitan at $2.40 per user per month paid annually, with a minimum of 25 users. At list price, a 10-person office would pay for 25 users, which is $60 a month. Ask TitanHQ or a partner whether a different arrangement is available to you.

### Does iBlockSpam sandbox attachments like SpamTitan?

No. iBlockSpam filters spam, viruses, malware, phishing and spoofing, and offers attachment-type filters and a Microsoft Office macro filter, but it does not detonate attachments in a sandbox. If sandboxing is a requirement, SpamTitan includes it.

### Can I try iBlockSpam the way SpamTitan offers a 14-day trial?

iBlockSpam has no free trial. Instead, a domain's first annual subscription has a 30-day money-back guarantee. You can also run our free tools, such as the Email Health Check, on your domain before you buy. SpamTitan has a 14-day trial, and the vendor says no payment card is needed.

### Is SpamTitan archiving included in the $2.40 price?

No. On TitanHQ's pricing page, archiving is a separate product, ArcTitan, listed at $3.94 per user per month paid annually, and encryption is EncryptTitan at $2.40. iBlockSpam keeps 30 days of message history and doesn't offer long-term archiving.

### How long does a move from SpamTitan to iBlockSpam take?

The change itself is an MX update plus platform steps, such as a Microsoft 365 inbound connector. Plan it over a few days: lower your MX TTL first, keep SpamTitan active until the old TTL has passed, then cancel. Most domains are set up in one session; that's our aim, not a guarantee.
