Frequently asked questions
Everything you need to know about the product and billing.
Klaviyo offers a free trial. You can create an account, edit and customize email templates, import and sync your data, and send emails with it. You can send a maximum of 500 emails to up to 250 contacts. You also receive 150 SMS credits. Once you exceed that limit, you will receive a prompt to upgrade your account by paying a fee.
Klaviyo was designed keeping eCommerce businesses in mind, while Mailmodo is an email marketing platform that caters to all kinds of organizations. For businesses that don’t sell physical products online, like service-based companies, Mailmodo has a range of features, such as AMP email interactivity and integrations with Hubspot, Google Sheets, Influencer Bit, and Pabbly to help you scale up.
Mailmodo is a better choice in terms of email deliverability. If you’re a Klaviyo user, your fluctuating email deliverability rates may be attributed to a low engagement history, poor domain reputation, or scammy email list. Mailmodo helps boost your email deliverability by giving you expert consultations, helping you with domain warm up, and removing spammers from our platform.
You can sign up for Omnisend’s free plan and send up to 500 emails monthly. However, if you find the trial plan too limiting, you can consider taking advantage of Mailmodo’s free trial plan.
If you’re not able to build complex workflows with Omnisend, it is likely that you’re among the many customers who have complained about its limited automation capabilities. If you’re looking for an automation solution that offers you pre-made workflows, custom triggers, and endless integrations, try Mailmodo. It’s a great Omnisend alternative.
Omnisend has a poor deliverability rate, which leads to your users’ low inbox placement rates. Want to achieve better email deliverability? You can rely on Mailmodo's dedicated servers, warmed up domain, and suppression management strategies.
