Multi-Store Accounts Comparison
For businesses that run multiple ecommerce brands at once, it’s important to be able to manage their multi-store accounts efficiently.

In this department, both tools have their advantages and drawbacks, which we outlined below.
Klaviyo Customer Support
Klaviyo provides several help channels, such as live chat, email, and an extensive selection of online resources. In a competition of Klaviyo vs Omnisend, providing free help resources in a great advantage.

However, with email service only available from 6 a.m. to 10 p.m. ET on weekdays and 10 a.m. to 4 p.m. ET on weekends, Klaviyo has a more constrained timeframe. Consumers in different time zones or experiencing urgent problems may find Klaviyo’s limited customer help hours problematic. Additionally, free account holders lose access to some support resources after 60 days, leaving them mostly dependent on email and the chatbot.
Omnisend Customer Support
Omnisend offers email and live chat support in case you need help with any of its functionality. Their Customer service is also available via a chatbot named Klara that works around the clock. A thorough knowledge library with articles, tutorials, and guides helps users solve problems.
Although customers value Omnisend’s support team’s promptness, there are drawbacks, including a lack of phone support, restricted live support hours, the possibility of delayed responses, and a reliance on automated help. This is a common disadvantage for both Omnisend and Klaviyo compared. All things considered, Omnisend provides a variety of support channels, yet consumers could experience difficulties with accessibility and personalized help.
Klaviyo vs Omnisend: platform with the best customer support:
