1. Choosing a template type
Before signing your document, you must first choose which template you want to use. This is selected via the ‘Template’ dropdown menu in the blue bar, as shown in the image below:
2. Add one or more signers
Here, you decide which recipients need to sign your selected document. Click on the ‘Add one or more signers’ bar as shown below:
You will then see the following screen:
Enter the name (and optionally the title, though this is not required) of the signer for the documents.
Next, enter the signer’s email address.
Once that information is added, you’ll need to decide how to notify the signer, how they should authenticate themselves, how they should sign, and whether they should receive a receipt.
Notification: | Authentication: | Signing: | Signer’s receipt: |
Here, you decide how the signer should be notified. Learn more here. | Authentication allows you to verify that the signer is indeed the person they claim to be. | Here, you choose the method the signer should use to sign the documents. | Here, you select the format in which the signer will receive their copy of the signed document. |
Once you have selected the above options, click the green button ‘Add Signer’. You have now added a signer.
⚠️ About SMS delivery to blacklisted countries
Please be aware that Addo Sign does not support SMS delivery to certain blacklisted countries:
Country | Country code |
Afghanistan | (+375) |
Belarus | (+93) |
Egypt | (+20) |
Indonesia | (+62) |
Mariana Islands | (+670) |
Kenya | (+254) |
This limitation applies to all use cases involving SMS:
Notifications: You cannot send SMS notifications to recipients with phone numbers from blacklisted countries.
Authentication: SMS cannot be used as an authentication method for phone numbers from these countries.
Signer's receipt: It is not possible to send the signed document via SMS to the signer if their phone number belongs to a blacklisted country.
Recipients of signed copy (third parties): Likewise, you cannot distribute a copy of the signed document via SMS to an external third party if the recipient’s number is from a blacklisted country.
If your recipients are affected by this restriction, we recommend using email as the alternative method for notifications, authentication, and delivery of signed documents.

3. Add files for signing
You need to click on the blue bar named ‘Drag files or click on +’.
You can now freely select the documents you wish to send for signing.
Note: You can only send documents in PDF format for signing. All other file types will be attached as appendices and cannot be signed using Addo Sign.
PDF form fields remain editable after signing. This is standard behavior. However, if any changes are made to the document after signing, including filling or modifying form fields, the digital signature will be broken and no longer valid.
After selecting the document(s) you wish to attach, click ‘Open’ (depending on your language settings). You can read more about how to change language settings here.
4. Message to signers
In this field, you have the option to send a message to the signer of the document. You can choose to write your own personal message or use one of the templates provided by the system. Learn more here.
5. Recipients of copy
If you need to send a copy of the signed documents to a third party, you can learn more here.
