Legalario Emails Electronic Signature for Anyone

Email redesign for Legalario's e-signature platform. Previous emails looked like spam. We redesigned invitations, reminders, and confirmation.

Cliente: Legalario
Industria: Legal Tech / Fraud — SaaS
Tiempo: 30 days
Impacto: +9% in Customer Love

Legalario redesigned transactional email opened on an iPhone — Mexican SMB signer previewing the list of documents to sign with the multilingual notification template, the NPS-saving customer-success rewrite that replaced the legacy one-size-fits-all mail across LATAM

The first impression of a digital product influences 70% of the likelihood that the user will use your product.

We serve a wide range of users—from fast food chain waiters to investors who use Legalario—so invitations to sign are not always understood or trigger the main JTBD: signing documents.

Reto

Universal notification: no technical jargon and easy to understand for any user.

As a general rule, any document signed with Legalario is legally valid. However, this essential rule is not clear to users who sign agreements through Legalario. It is also unclear how to start signing a document, as the current emails look like spam.

Aventura

Defining top 3 challenges identified.

Three redesigned emails — invitation, verification code, and signed confirmation — shown on phones with orange, green and blue backgrounds

Signing invitation email on a phone over an orange background

Verification code email on a phone over a green background

Signed-documents confirmation email on a phone over a blue background

Our notifications must be as clear and understandable as the service they already use.

Three pillars we aligned on — Customer Success & NPS, Legal validity & Multilingual, Sign a document

01
Customer Success & NPS
We work collaboratively between the Sales and Customer Success teams to understand how to optimize notifications and document signing invitations.
02
Legal Validity & Multilingual
42% of users requested multilingual notifications.
03
Sign a document
68% of users did not understand how to start signing a document.

Seeing the mountain

We understand that the current design needs to be updated.

We analyze the current experience end-to-end and see the need to redesign it from scratch. At the same time, development reports technical debt and unsupported use cases that we must address.

We improved the usability and components of the Design System to enable rapid testing.

We leverage AB testing with short sprints to iterate quickly and improve conversion.

A GREAT result in a very short time

Together with Engineering, we improved all notifications so that the Jobs To Be Done were clearer for our customers and users.

We cover new use cases

The restructuring allowed us to identify frequent use cases in certain user segments that were not covered: mass signing of documents, an explanation of the documents required for signing, and mass signing for recurring signers.

Mass signing of documents — first version on a pink background vs. last version on a mint background — 01 — Mass signing of documents

Explanation of documents required for signing — phone showing identification options and signing method preferences — 02 — Explanation of documents required for signing

Enabled for each customer based on their account settings.

Mass signing of documents for recurring signers — a phone listing several pending contracts with a single sign-all action — 03 — Mass signing of documents for recurring signers

Recurring signers no longer have to sign each file separately: they now see a list of pending files and can sign them one by one or all at once.

We made great progress in two sprints

+31%: revenue In conjunction with the Electronic Signature project.
+12%: signed documents By supporting three languages, our customers expanded their use of the platform.
+9%: Customer Love The whole new process is incredibly easier for anyone to complete.
