The best e-signature software for marketing agencies
An agency doesn't just need a signature box — it needs documents that look like its brand, not the vendor's. Proposals, statements of work, retainer agreements: each should carry your logo and colors, build from a reusable template, and tell you when a client opened it. So the criterion that matters most here isn't raw signing — it's branded templates and proposal workflow, the part that makes an agency look polished and lets you reuse work across clients. We reweighted the rubric around that.
The criterion that matters most for an agency is branded, reusable templates — white-labeled proposals and contracts that carry your brand, not the tool's — because agencies send a high volume of client documents and live or die on looking professional. Volume value and client management come next. See the full rubric →

PandaDoc
Best for agency proposals
PandaDoc is built for exactly the agency workflow: design a branded proposal or SOW once, reuse it across clients, and watch analytics tell you when a prospect opened it and how long they lingered on the price. Signing is just the final step of a polished, on-brand document. Unlimited sending means a busy agency never hits a cap. It costs more than a bare signing tool, and that's the point — you're paying for the proposal engine, not the pen.
If a client insists on the name they recognize, DocuSign is the safe, universally trusted choice, and nothing signs more reliably. For an agency the catch is the envelope cap — roughly 100 per user per year on Standard and Business Pro — which a high-volume shop can outgrow, plus weaker proposal branding than PandaDoc. Great as a pure signing layer; less so as your proposal tool.
At $8 per user a month with unlimited sending and custom branding, SignNow gives a cost-conscious agency most of what it needs for the least money. It does templates and team management well. What it lacks is PandaDoc's rich proposal experience and analytics, so if your documents are straightforward contracts rather than designed proposals, the savings are real and worth it.
If your designers already live in Adobe and your deliverables are polished PDFs, Acrobat Sign keeps everything in one ecosystem — edit the PDF and send it for signature without leaving Acrobat. It's a strong fit for that specific shop. As a standalone proposal-and-signing platform for an agency, it's less focused than PandaDoc, and the e-signature features are bundled into Acrobat plans rather than sold cleanly on their own.
Dropbox Sign is the most pleasant tool here to actually use — clean, fast, with tidy templates and light branding. For a small agency that mainly needs contracts signed without fuss, it's a joy. The ceiling is proposals: there's no rich proposal builder or deep analytics, and the two-user minimum on higher plans nudges the real cost up. Lovely for signing, thin for selling.
Signaturely is the friendly, no-frills entry point — easy to learn, cheap, with unlimited signature requests on paid plans. For a one-person agency just needing contracts signed, it does the job. But it's the wrong-fit trap if you want branded proposals and analytics: there's no real proposal builder, and you'll outgrow it the moment client documents need to look designed rather than functional.
What should a marketing agency look for in e-signature software?
Look past the signature itself. An agency lives on branded, reusable templates (proposals, SOWs and retainers that carry your logo, not the vendor's), document analytics that show when a client opened and read a proposal, and the volume to send dozens a month without hitting a cap. Pure-signing tools handle the last step; an agency needs the whole proposal-to-signature workflow, which is why PandaDoc leads here.
Does DocuSign limit how many documents I can send?
Yes — and agencies are exactly who gets caught. DocuSign's Standard and Business Pro plans cap you at roughly 100 envelopes per user per year (June 2026). A busy agency sending proposals and contracts across many clients can blow through that, then face overage costs or a forced upgrade. PandaDoc and SignNow offer unlimited sending on their paid plans, which suits high-volume agencies better.
Can clients sign without creating an account?
Yes, with every tool on this list. Your client gets an email, opens the document in a browser, and signs — no account, no app, no friction. That's table stakes for e-signature software in 2026; if a tool made signers register, it wouldn't make this ranking.
What's the cheapest e-signature option for a small agency?
SignNow's Business plan at $8/user/month (annual) is the lowest real per-seat cost with unlimited sending, and Signaturely's $20/month Personal plan is a fine entry point for a solo shop. But weigh that against branding and proposal features: saving a few dollars on a tool that makes your client documents look generic can cost you more in lost polish than you save.
