What is Substack?

This website is hosted on Substack. When you subscribe to our service, a Substack account is created for you under the email address used to subscribe.

How do I sign into my Substack account?

You can manage your Letters subscription directly at this link:

https://zero2hero.substack.com/account

If you can’t sign into your account, you may have subscribed with a misspelled email address. Get in touch with the Substack Support team here – they can help you with any login issues.

How do I receive newsletters?

You can see our newsletters here: https://zero2hero.substack.com/newsletters

When you subscribe as a free or paid reader, you’ll automatically receive a Welcome email.

If you didn’t receive one, you can send yourself a test email to see whether there is an email delivery issue.

On your Manage subscription page, click on “If you’re having email delivery issues”. On the next page, select “Send test email to [your email will appear automatically here].

You can also send a test email directly at this link: https://zero2hero.substack.com/account/email-test

If you don’t receive the test email, it may be in your Promotions or Spam folders or your email provider may have blocked emails from us. Get in touch with the Substack Support team here if you believe your email has been blocked.

I used to receive emails from you but they’ve stopped– what happened?

Sometimes a newsletter may appear in your email’s Promotions or Spam folders and we recommend checking both places.

If the email is in Promotions, we recommend dragging the email back to the Inbox.

If the email is in Spam, please mark this address as “not spam” and add our email address to your contact list. All posts will be sent from zero2hero@substack.com
If you’ve checked both places, it’s possible that a previous email was marked as Spam and your email provider blocked us from sending further emails. Get in touch with the Substack Support team here if you believe your email has been blocked.

How do I unsubscribe?

Replying “unsubscribe” or “cancel” to an email newsletter will not unsubscribe you nor cancel your paid subscription.

Instead, visit your Manage Subscription page and disable the toggles for the notifications you’d no longer like to receive. If you’d like to completely unsubscribe from Letters, click on the red “Unsubscribe” button.

How do I cancel my paid subscription?

We’re sorry to see you go but if you’d like to cancel your paid subscription, visit your Manage Subscription page. In the Account actions section, click on “To cancel your paid subscription, click here”.

On the next step, you can pause your subscription. If you’d like to no longer receive any posts and cancel your monthly or annual subscription, click “Cancel Subscription”.
