Support/Technical FAQs
For administrative customer service inquiries, please contact Substack support directly at https://substack.com/support or email support@tematicaresearch.com.
I paid, but I don’t have access. Why can’t I see the articles?
Substack ties your subscription to the email address associated with your account. If you signed up for Tematica’s EPS Diplomats with a different email address than the one you use to log in to Substack, you will not see paid Tematica content. You will need to log in to Substack with the same email address you used to sign up.
How do I manage my subscription?
You can find detailed account management instructions here. In general, for administrative or customer support inquiries, please contact Substack support directly at https://substack.com/support.

Is there a price difference between buying through the iPhone Substack app versus the website?
Yes. Subscriptions purchased through the iPhone Substack app (via Apple’s In-App Purchase system) are subject to a markup fee imposed by Apple, which is passed on to the subscriber and results in a higher price.
To receive the lowest available subscription price, we strongly recommend that all users—both U.S. and international—subscribe directly through Tematica’s EPS Diplomats website, or the main Substack website, rather than through the mobile app. You do not need to be on a laptop or desktop in order to do this. Signing up through a mobile phone internet browser (e.g., via Safari or Chrome) will also avoid the Apple markup.
Why is my charge higher than the listed subscription price?
If your billing address is in New York, Connecticut, New Jersey, Texas, Colorado, Tennessee, Maryland, or Puerto Rico, the difference is likely state or territory sales tax applied at checkout. You can view an itemized receipt by following the instructions on Substack Support.
Can you send me a receipt for accounting and reimbursement purposes?
You can find your receipt in your email or by following the instructions on Substack Support.
As a reminder, all professional and institutional users must be on our institutional tier, where you will be better served and brought into alignment with our Terms of Service.
My credit card lapsed. Can I get my old price back?
It is the subscriber’s responsibility to keep their payment method current. There is no guarantee that we can reset the subscription price to the grandfathered rate.
I’m an institutional investor. Can I subscribe to the research via Substack?
No. Tematica Research maintains a strict commercial policy that separates retail from institutional subscribers in accordance with standard industry practice. Institutional and professional investors should contact sales@tematicaresearch.com for more information about our institutional platform.
How should I engage in the Tematica Research Substack chat?
The chat is organized in posts and reply threads. Replies to posts must be related to the topic of the post. Additional insights, thoughtful disagreement, alternative viewpoints, and discussion are always welcome and valued. Trolling, spam, IP violations, and off-topic comments are not tolerated. In general, users engaging in activity that is counterproductive and disruptive to the readership will be banned. We aim to enforce chat moderation for the benefit of the overall subscriber base.
General user feedback can be submitted to tematica@substack.com.
How should I think about implementing the EPS Diplomats or other Tematica targeted and thematic baskets?
We see these models as a means to best track the strategies presented. The decision to implement any of our model portfolios – and the method of implementation – is entirely up to you.
We make our model portfolios available; however, their availability should not be construed as a recommendation or endorsement.
