DocSend shares documents by link and shows who read them. Sellizer runs the whole proposal: an SMS on the first open, heatmaps and session recordings, Priority and Engagement scores, and automated follow-ups.
Start freeBoth send a document as a link and show who opened it. The difference is whether you protect files or take a proposal all the way to the client's decision.
Password-protected links, NDA and watermark, data rooms and an access log. A good fit for investor talks and due diligence.
A text message on first open, heatmaps and session replays help you pick the moment and the topic. Follow-ups go out on their own.
Share documents that need an NDA and a data room in DocSend. Send client proposals through Sellizer and know when to call.

Maciej Zagórowski
CEO Fabryka e-biznesu
Thanks to Sellizer, I know which parts of my proposals are the most interesting for my customers - it gives me great basis to start a valuable conversation. I can also contact with clients in the best time - when they have my proposal right in front of them. Such combination made it so much easier for me to sell projects.
Damian Rams
Digital Analytics Consultant, DamianRams.pl
We like clever solutions. Just like in Sellizer, we believe that the time of contact with the customer really makes a big difference, so we decided to integrate our tools. Thus, Sellizer user gets a SMS message about the opening of the proposal and statistics and recipients of their proposals can ask for contact via Callpage widget. Awesome!
Sergey Butko
CMO & Co-Founder Callpage
Using Sellizer has improved our communication, both within and outside the company. In our internal communication, we use Sellizer to send important documents to ensure that they have not been skipped or missed among many other messages. Moreover, thanks to the use of the tool in communication with potential partners, we can see at what stage our relationship is.
Tomasz Świeboda
Managing Partner Inovo.vc
LinkedIn is the most important channel for communicating with clients. Sellizer allows me to quickly and conveniently send presentations and proposals, and what’s most important, allows me to react quickly to their opening, analyse interest in them and consequently conduct valuable business conversations. I recommend.
Marcin Małaszuk
Sellizer helps us respond to questions from our customers at the right time. Thanks to that we give added value already at the sales stage which allows us to build a relationship with the customer from the very beginning. This is very valuable to us.
Łukasz Białonoga
Although Sellizer can at first glance be seen as a tool only for sending proposals, I can certainly confirm that it also works for sending sales folders, contracts and other documents. Thanks to this, we have a real-time preview of what is the most valuable to the customer in each document (on which parts they spent most of the time) and what needs to be improved.
Michał Boniecki
Sellizer enables a thorough analysis of the customer in terms of interest in our proposal, which helps us save time in the further parts of sales process. When receiving information on how long the customer has been reading each pages of the proposal, I can predict whether the sales process will continue or our proposal is just a market recognition for statistical purposes of the potential customer.
Bartosz Makles
Sellizer has become an inseparable tool for us in communication on several levels. As an intermediary in the logistics industry, we come into contact with both operators and their customers. Sellizer allows us to work with both the first (reporting) and the second (sending proposals) Partners. Thanks to the systematisation and transparency of the activities in Sellizer, we have been able to significantly increase the rate of acquired customers.
Mariusz Korzeniecki
Until now, our knowledge has been ending at the stage of sending the proposal - and thanks to Sellizer - now this is the point where the acquisition of the greatest amount of knowledge about the client begins which allows the marketing team to understand better the needs and match the proposal content to the customers and sales team to contact the customers always at the right time. Thanks to the opportunities that Sellizer gives us, we can everyday increase our chances in a game called sales.
Michał Czuba
Very often we wondered why, despite sending a large number of proposals, many of them still remained unanswered. Thanks to Sellizer, we have structured our sales process, organized sending proposals and gained awareness of their quality. Now we can easily track which parts of our proposals are the most valuable for our customers and continuously improve them. I am pleased that with Sellizer we make better use of our time as well as the potential of our customers.
Grzegorz Jaskot
We sincerely recommend Sellizer. It helps our sales team in daily duties and prioritizing customers. But that's not all. At the department level, it gives us the opportunity to improve the entire sales process based on easily measurable criteria.
Michał Drozda
Thanks to Sellizer we have optimized our process of preparing proposals. With data sets we create tailor-made proposals to meet customers’ needs and expectations, which improves the conversion rate. I’d recommend it to anyone!

Pick Sellizer if you send a proposal and then have to decide who to call, when and with what question.
Pick DocSend if you share finished documents and need to know who has access to them.
Share investor and due diligence documents in DocSend, and send sales proposals through Sellizer.
DocSend shares a document by link and measures who read it. Sellizer runs the whole proposal: it sends it, texts you on the first open, shows a heatmap and a session recording, gives Priority and Engagement scores, and then follows up automatically.
No. DocSend sends notifications in real time, but by email only. Sellizer texts you on the first open and emails you on every subsequent one.
No. DocSend has e-signature - capped at 4 signatures a month on the lowest tier, unlimited above that. If signing the proposal matters to you, that is an argument for DocSend.
DocSend costs EUR 9, 40, 135 and 165 per month, Sellizer USD 17.60 on Solo and USD 28.00 on Team. The team's sheet records these in different currencies, so treat the comparison as indicative. It is also worth checking how many DocSend features only switch on in higher plans. As of August 2026.
When you need an e-signature on the document, or controlled access to the proposal: a password and a list of allowed addresses, an NDA before access, a dynamic watermark, folder and file permissions, an audit log and company-account login. On top of that a sales room with a shared action plan and a question asked inside the proposal window - Sellizer has none of these. Choose Sellizer when you want to run the proposal from send to decision in one place.
