With Klaviyo, you can trigger an autoresponder email sequence for basically any event you can measure (as long as you have the contact's email address). This opens up all kinds of possibilities, such as abandoned cart emails, thank you emails after a purchase, customer satisfaction surveys after a time window after a purchase, and cross-sell emails given a certain item purchased.
Thrive Architect is a page builder for your WordPress site and only works within WP unlike GetResponse. Yes you need ThriveLeads to capture emails (through popups, inline forms, sticky bars, etc) and build your list on from WordPress. You’ll have to integrate it with your Autoresponder (GetResponse). If you create your landing pages on GetResponse and want to use it on your WordPress site – you can use their WordPress plugin to add your GetResponse landing page to your WordPress site as a subpage. Else I’d build it on WordPress using Thrive.
There are literally thousands of plugins available that help extend the functionality of WordPress. Your website will depend on several plugins, depending on what you need done.

Also, too many plugins is a management headache along with the risk of not being compatible with the latest versions of WordPress.

Say if you have 1000 contacts, and upgrade to Marketing Starter, you can send 5 times that number in sends so email marketing send limit per month will be 5000.
