SellerThanks vs 3Dsellers: a simple alternative for small eBay sellers
If you're searching for a 3Dsellers alternative, you probably want automatic messages to your eBay buyers without paying for, or learning, a whole platform. Here's an honest comparison, including when 3Dsellers is the better choice.
The short version
- 3Dsellers is an all-in-one e-commerce platform: listing tools, automatic messages, feedback reminders, an optional helpdesk, and connections to other marketplaces on its top plan.
- SellerThanks does one job: automatic, personalised messages to your eBay buyers after payment, when you dispatch, and a feedback reminder, with an optional size guide picture. It's built by a UK eBay seller for small sellers.

Choose 3Dsellers if…
- You sell on several marketplaces and want them managed in one place.
- You have a team answering buyer messages and want a shared helpdesk.
- You want listing, repricing and marketing tools as well as messages.
Choose SellerThanks if…
- You sell on eBay and simply want every buyer thanked, updated and reminded about feedback, automatically.
- You have lots of listings but a small budget: there's one price, however many listings you have.
- You sell items where size matters, and want buyers to see the size they ordered next to a 50p coin.
- You'd like something you can set up in a few minutes and then forget about.
Switching is simple
SellerThanks only needs your eBay connection and your message wording. If you already have messages you're happy with, copy them in and swap the buyer's details for placeholders such as {buyer_first_name} and {tracking_number}. Switch off automatic messages in your old tool first, so buyers don't get two of everything.

Let SellerThanks send these for you. Write your messages once and they're sent automatically to every buyer, after payment, when you dispatch, and as a polite feedback reminder, personalised with their name and what they bought.
