Straight Mail is a small UK-built outreach tool that does one job: send plain-text cold email sequences with automated follow-ups through a mailbox you already own. Its published pricing page lists a single tier at £0 per month. That combination — free, minimal, and almost entirely undocumented by anyone other than the vendor — shapes both what this review can tell you and what it can't.
| Best for | Solo founders and freelancers sending low-volume outreach from one or two existing mailboxes |
| Starting price | £0/month (Bronze, the only tier listed) |
| Real cost | £0 for the software, plus whatever you already pay for mailboxes, domains, and lead data |
| Setup speed | Vendor advertises setup in minutes; you connect Outlook or SMTP/IMAP credentials yourself |
| Standout feature | Plain-text-first sending with no HTML templating layer |
| Biggest caveat | No inbox infrastructure, no warmup, and no independent reviews anywhere we could find |
| Third-party rating | None — no G2, Trustpilot, or Reddit presence located |
It sits in the sequencer half of the cold email stack, not the infrastructure half. You bring the mailbox; Straight Mail schedules the messages, spaces out the follow-ups, watches for replies, and reports on what happened. The vendor's framing is deliberately anti-feature-bloat: plain text rather than designed HTML, a stripped-back dashboard rather than a sales engagement suite.
That framing is not just aesthetic. Plain-text messages avoid the tracking pixels and heavy markup that make bulk-mailer output easy for filters to classify. Whether that alone improves placement is contested — sender reputation, domain age, and volume ramp matter far more — but it is a defensible default for one-to-one style outreach.
Connect an Outlook account or supply custom SMTP and IMAP credentials, build a sequence with an initial message and timed follow-ups, add personalization variables, and let it send. IMAP access is what enables reply detection, so the tool can stop a sequence when a prospect responds.
Because sending runs through your own mailbox, your daily limits are your provider's limits, not the tool's. Google and Microsoft both cap outbound volume per account, and those caps — not the £0 price — are the real ceiling on how much you can send.
| Plan | Price | Included |
|---|---|---|
| Bronze | £0/month | Unlimited sending (advertised), unlimited profiles, dynamic emails, follow-ups, reports and analytics |
Only the Bronze tier appears on the pricing page at the time of writing. There is no published paid tier, no per-seat charge, and no per-mailbox charge.
The real-cost math is therefore about everything the tool doesn't supply. A working cold email setup still needs sending domains (roughly $10–15 each per year), mailboxes (Google Workspace at retail is around $7 per user per month), warmup for new accounts, and a lead source. Straight Mail covers none of that. If you already have a mailbox and a modest list, your marginal cost really is zero. If you're starting from nothing, the software was never the expensive part — and a free sequencer does nothing to change that bill.
Treat "unlimited sending" as a description of the vendor's own metering rather than a capability. Your mailbox provider will throttle you long before Straight Mail does.
We confirmed directly from the vendor's site: the plain-text sequencing model, automated follow-ups, reply tracking and analytics, Outlook and custom SMTP/IMAP connection, GDPR positioning, and the single £0 Bronze tier.
We could not verify anything independent. Searches across review platforms and community sources returned no G2 profile, no Trustpilot listing, and no Reddit discussion of Straight Mail. There are no user-reported deliverability results, no support-responsiveness reports, and no public account of how the product behaves at any meaningful volume. Nor does the site publish company details, team information, or a track record.
That absence is not evidence of a bad product — it is what a very small or very new tool looks like. But it does mean you would be trusting an unaudited third party with mailbox credentials that grant read and send access to your email. For a free product with no visible support commitment, that is the trade to weigh. Use a dedicated outreach mailbox rather than your primary one, and an app password where your provider supports it.
Pros
Cons
If the appeal is "cheap and simple," these are the realistic comparisons:
Good fit: a founder or freelancer sending twenty to fifty personalized emails a week from an existing mailbox, who wants follow-ups automated and replies tracked without paying a monthly subscription or learning a platform. At £0 the experiment costs you nothing but setup time, and the plain-text model fits that sending style well.
Poor fit: anyone running agency-scale outbound across rotated inboxes; teams that need warmup, domain management, or deliverability monitoring bundled in; organizations with security review requirements, which an unaudited vendor with no published company details will not clear; and anyone who needs support they can escalate to mid-campaign.
