3. Select the Aliases tab.

4. Click Edit next to the desired alias.

You will always have access to all emails sent by others.

How can I change the default From address when I create a new draft?

Click your name in the bottom left corner, then Preferences, and search for “default send”, you will see the options below to change the Default sender address, which is the default address set in your From field when you start a draft:

This setting is personal, each user in your organization is free to define it as they like.

How can I prevent an alias to be used when I reply to emails?

You can tell Missive to never automatically select a particular From address (known as an “alias”) when replying/composing a new email. You’ll still be able to manually set this alias in your From field if you need to.

1. Go to Settings > Accounts.

2. Select the desired email account.

3. Select the Aliases tab.

4. Click Edit next to the desired alias.

5. Check the option that says, “Never automatically select as the From address when composing an email”.

How do email aliases compare to email proxies?

In most everyday and business scenarios, users are far more likely to use email aliases than email proxies. The creation and configuration of email aliases or email proxies happens at the email provider level.

Here’s why:

• Email aliases are built into almost every email provider (Google Workspace, Microsoft 365, iCloud, etc.) and are commonly used for team roles (e.g., support@, billing@), personal organization, and filtering. They’re simple, familiar, and don’t change the sender’s identity.

• Email proxies are more niche and are mainly used for privacy, security, or anonymity. Tools like Apple’s Hide My Email, Firefox Relay, or burner-style email services are proxies — still far less common in business workflows. They are created and managed outside Missive. Missive simply receives messages forwarded from those proxy addresses.

Signatures

Can I use a specific signature on the mobile app?

Missive does not offer a way to set mobile-specific signatures right now. However, you can set up any number of aliases for each of your email accounts, and each alias can have a different signature. You can give your alias a clear description like “Mobile signature”:

Even if you don’t have different alias addresses, you can create multiple aliases with the same Address and Name, just to set a different description and signature.

Assuming you send more emails from your computer, we suggest you set your desktop signature version on your default alias. Then when you send an email from mobile, you can manually switch to your mobile alias in the From field, which will change the signature used.

Can I use custom values within shared email signatures?

You can use custom fields within shared signatures. You can use them as:

{{ user.custom.field_name }}

If your custom field name is, for example, Job title, then it would be:

{{ user.custom.job_title }}

How can I add multiple phone numbers to a signature?

You can use variables to display multiple phone numbers in your email signature. For example, if you want to add your work and mobile phone number you can use these:

{{ user.work.phone_number }}

{{ user.mobile.phone_number }}

How can I define multiple signatures for the same email address?

In Missive, you can setup any number of aliases for each of your email accounts, and each alias can have a different signature.

Even if you don’t have different alias addresses, you can create multiple aliases with the same Address and Name, just for the purpose of setting a different signature for each.

Here’s where to add aliases the in Accounts settings:

Each alias and signature can have their own unique description to help you pick the right one in the draft composer:

You can edit your alias description, in the alias edit menu:

To edit the signature of each of those aliases, click on the Signature tab:

How can I make sure the image in my signature doesn't appear as an attachment?

If you want to include an image in your email signature, it's better to use an HTML signature instead of attaching the image directly. This will help prevent your email from being flagged as spam by some email providers.

To do this, you can create an HTML signature and add an <img> tag with the URL of your image hosted on the web. This way, the image will be displayed in the signature without being attached to the email itself.

How to insert a user avatar in a managed signature?

You need to edit your managed signature in HTML mode, and add an image element with the variable {{ user.avatar_url }} as its source. This will show the image your users have uploaded as their Missive avatar. It would look something like this:

How to limit the size of an image in my email signature

1. Switch the signature editor to the HTML mode.

2. Add a max-width: 400px to the style element of the img tag.

3. Increment/decrement the value of max-width based on the desired result.

Why are my signature HTML tags stripped?

Missive strips HMTL tags that are not supported by the majority of email clients. Your signature HTML code probably uses modern tags known to not be well supported by email clients.

You might try to inline your styles. Paste your code in this tool. The output HTML might be supported by Missive.

Why can't I edit my signature in my draft composer?

If you can't change your signature while drafting an email, it's likely because your signature is in the HTML format. This format can't be altered in the draft composer.

To switch formats, go to Settings > Signatures, click Edit, and look for the format toggle at the bottom of the Content field.

Be aware that if you switch from HTML to Rich Text, you might encounter some unexpected visual changes, especially if your signature's HTML code is too complex for Rich text.

Why can't I edit my signature in my settings?

You most likely have a managed signature. This means only Admins or Owners can make changes to it. You may contact them to request a change.
