    Helpful email tool but also pricey

    Date: Oct 19 2021
    Summary

    A very powerful email marketing platform, good templates and sequences as well as integrations with platforms like Shopify. However given the strength of the platform it is expensive.

    Positive

    A powerful email platform, their templates and starter flows are good to get started with initial email sequences. Their editor is pretty good and I like their integrations into Shopify for things like coupon codes, cart abandonment emails etc.

    Negative

    Can sometimes be a little bit hard to use and setup, but once you understand the nuances it is fine. The platform is expensive based on newsletter subscriber volume as compared to other platforms, in some ways it may be best to hire someone to manage it to get the most value out of it.

    It makes it all better when it comes to email marketing and e-commerce

    Date: Apr 24 2021

Klaviyo makes pulling data from our e-commerce platform and other marketing tools very quick and easy, plus its ability to monitor revenue, optimize flows, and email marketing processes saves time and energy for our entire marketing team. Our experience using Klaviyo has been quite satisfactory; its smooth integration and other tools make life easier for my organization's marketing team.

    I like Klaviyo and how well it syncs with other tools, especially e-commerce and other marketing platforms, to make it easy to pull data from the media it integrates with, facilitate segmentation, create automated flows and strengthen email marketing in our organization. It simplifies everything about email marketing, is very easy to use, has good templates, automation, and more.

    Email marketing is no longer difficult with Klaviyo

    Date: Mar 30 2021
    Summary

    Although a large investment must be provided to exploit its functionalities, Klaviyo is a tool that allows extending market relationships between users and companies with its message automation and persistent contact with customers to cover all their needs. Klaviyo is an essential tool in advertising.

    Positive

    The main advantage is that it segments a formidable amount of users to apply promotional and marketing methods. It has email autoresponder tools that we can pre-build and import to your database to automate customer relationships.

    Negative

    However, it does not offer customer survey options to determine what their needs are and to target our opportunities with them. On the other hand, to have a greater scope of access to contacts in your database you must pay subscriptions that depend on the number of users provided, but their costs are very high compared to other applications.
