The MySignature alternative with no subscription

Updated June 2026

MySignature is one of the better-known email signature generators, and it does a lot: signature templates, email open tracking, banner analytics, digital business cards, team management. If you need all of that, it may genuinely be the right tool — more on that below.

But most people searching for a MySignature alternative are here for one reason: they want a signature, not a subscription. An email signature is a static asset. You make it once, you tweak it when your title or phone number changes, and otherwise it just sits in your Gmail or Outlook settings. Paying for it every month feels wrong because, structurally, it is a one-time job.

The pricing models, side by side

As of June 2026, MySignature’s pricing page lists a Professional plan at $7 per user/month billed yearly (roughly $84/year) and a Teams plan at $6 per user/month billed yearly. The free plan gives you one basic signature per email address with limited functions. MySignature has at various points also sold lifetime packages through third-party deal sites, but the core product today is a per-user annual subscription.

OnceSig takes the opposite approach: Personal is $9 one-time (launch price; regular $15) for one signature with clean export forever, and Pro is $19 one-time (regular $29) for up to 10 saved signatures. Both come with a 14-day money-back guarantee. Full details are on the pricing page.

Over three years, that’s roughly $252 for MySignature Professional versus $9, once, for OnceSig Personal.

A note on the subscription model in practice: any auto-renewing product carries a structural risk — the trial that quietly converts, the renewal charge you forgot was coming, the cancellation flow you have to go find. That isn’t a knock on MySignature specifically; it’s how recurring billing works everywhere. A one-time purchase simply can’t do that to you. There is nothing to renew, nothing to cancel, and no card on file.

What you actually get: HTML that survives Outlook

A signature generator lives or dies on how its output renders, and Outlook’s Word-based rendering engine is the usual killer. Every one of OnceSig’s 12 templates is engineered specifically for it:

• Table-based layout with inline styles only — no stylesheet dependencies for Outlook to strip.
• No <p> tags, which eliminates Outlook’s notorious double-spacing.
• mso-line-height-rule: exactly on every line-height, so spacing doesn’t drift.
• Images with explicit width/height attributes and CSS dimensions, so logos and headshots stay sharp on high-DPI screens instead of scaling blurry.
• Dark-mode-safe colors and output that stays under Gmail’s 10,000-character signature limit.

When you’re done, you either copy the signature as rich text and paste it straight into Gmail or Outlook settings, or download a .htm file for classic Outlook’s %APPDATA%\Microsoft\Signatures folder. There are step-by-step install guides for Gmail and classic Outlook, plus new Outlook, Outlook on the web, Apple Mail, and Thunderbird.

No account, and your data stays in your browser

OnceSig has no signup flow at all. Your signature data is stored in your browser’s localStorage — it never touches a server. The editor is fully functional for everyone before any payment; free exports just carry a small “Made with OnceSig” credit line until a license key unlocks clean export. Checkout runs through Polar as merchant of record, so the only thing you ever hand over is a payment at the moment you choose to make one.

When MySignature is the better choice

An honest comparison cuts both ways. MySignature is the stronger pick if:

• You manage signatures for a team. OnceSig has no central dashboard or user management; MySignature’s Teams plan exists exactly for deploying unified signatures across an organization.
• You want email tracking and banner analytics. MySignature’s paid plans track opens and link clicks and report on banner campaign performance. OnceSig deliberately has none of that — no tracking pixels in your signature, but also no data.
• You run rotating marketing banners or want digital business cards. Those are MySignature features OnceSig doesn’t attempt.
• You want a larger template catalog with AI-assisted design tweaks.

If those capabilities are worth a recurring per-user fee to you, subscribe to MySignature with a clear conscience.

If what you want is one excellent signature that renders correctly in Outlook and Gmail, that you can edit forever, from a tool that never asks for your email address — open the OnceSig editor, build it for free, and pay $9 once if you like the result.
