Sellizer is a comprehensive sales supporting tool that will notify you when a customer opens your proposal and provide key statistics that you have never had access to.

SMS and email notifications about every opening of proposal

Are you wondering whether your customers had enough time to read your proposal or maybe they did it right after receiving it and already forgot everything? You don't need to guess or worry anymore!

Complex proposals' analytics:

Until now, you learned second-handed about the customer's opinion about your proposal - you knew as much as they told you. The problem is that 'consumers don't think how they feel, they don't say what they think and they don't do what they say' (David Ogilvy).

100% reliable real-time statistics:

5… 4… 3… 2… 1… New data! Statistics are worth their weight in gold because each piece of information increases your chance of successful sale and profit. We know that up-to-date data is the most valuable so we refresh it for you in real time with tremendous frequency - every 5 seconds!

Email open tracking:

Clients don't respond? Nothing new but for sure you wonder if they even opened your email. You've probably already used tools that inform you about email opening - you can find them in your email client or in the form of external plugins. However, you have noticed that their effectiveness is not entirely certain. We have a better solution.
