Affiliate Disclosure
Links in the notes go to the company's site so you can read the price there. HubSpot's Marketing Hub prices are on HubSpot's product page. Mailchimp's Standard price is on Mailchimp's pricing page.
If one of those links later pays Markettrellis a commission, the page will say so. The price next to the link still has to be the company's price. A commission does not change Mailchimp's 500-contact line, and it does not erase HubSpot's $890 and $3,600 tiers in order to leave only the $20 seat.
Your invoice comes from the company. Markettrellis does not add a charge on top.
