Constant Contact
Constant Contact is great when trying to target specific market segments. We typically like to segment our master list by region, but also have product segments, as well. They do provide pre-made segments to start you off too.We don't usually use their email builder, we find others to be more flexible, intuitive, and have more variety. We do prefer emailing from Constant Contact, however.

Klaviyo is really built for converting so if you are sending informational content either to your subscribers or internal comms, it is better to look elsewhere. If you send an email of this kind, people will not click and purchase and it will bring down your overall analytics to seem like your click-through, purchase values, etc. rates are low. Klaviyo is great however at flows and getting people engaged when they first subscribe or take certain actions (browse abandonment, cart abandonment, welcome series, etc.)

Constant Contact
- You can accomplish quite a bit using the drag and drop interface, so there is less custom HTML required.
- Easy to use for folks who are not tech savvy.
- Very quick upload speed for contact lists when compared with other email marketing vendors.
- Easy to customize contact lists.
- Displays much more consistently across different email clients when compared with other email marketing vendors.

- Email automation that nurtured new prospects with education and promotion content.
- List segmentation. We could segment our list by behavior, purchase history and by demographics. This gave us more views into the customer segmentation.
- Promotion emails. the high delivery rate of Flash sales, discounts, and promotions that drove sales
- SMS messaging. We could time SMS messaging to be aligned with email promotion to give a more omni marketing approach to CRM
- Reporting. Klavio provided excellent reporting by campaign and marketing period. It was able to track open rate, CTR, conversion and revenue.
- Creative Management. Klavio allowed us to store graphics from previous campaigns and use them in future marketing efforts
- Campaign Builder. the email builder mechanism is outstanding allowing for graphic, text, shapes and images all to be incorporated in HTML emails
- Testing. The AB testing function allowed for campaign optimization

Cons
Constant Contact
- The interface is definitely a bit difficult to use and it takes some getting used to.
- More customization and exporting of html would be awesome.
- They could expand on features that other email marketing software has such as tying in with social media, more flows, etc.

- more access to customer service via phone that instead of live chat
- segments could be easier to create if there was a clone functionality! I waste a lot of time creating segments that would be saved if I could clone and make edits from previous work I've done
- there should be functionality to show the over email size before sending, to ensure emails aren't cut off at the end

There is no doubt that we are going to renew Constant Contact. We have not just invested a lot of time in learning and creating a great looking product but we have developed a strong database of information that allows us to track how we are doing for each newsletter. This supports our goals of creating products that residents desire and are excited to receive.

Klaviyo is simply a great solution for e-com email marketing & customer relationship management:
- User journey visibility: We can see our clients' customers on their individual user journeys (open email, site visits) to better understand and accommodate your customers.
- Flow automation: Creating automated emails that follow up with new leads, those who abandoned carts, purchased.
- Email design: So easy to use, and more friendly than some other visual builders that we've used.
- Metrics visibility: We can see our clients' metrics very easily and adjust efforts accordingly.

There is always room for improvement. I don't know how they test their systems, but they should invite not-so computer savvy people to test it. If I, as an expert have problems, they need to think like the technophobe. Since I've used Constant Contact in the past as part of my former employment, I have not viewed any of the tutorials and just jumped in to work on my client's newsletter. With that said, I found some areas easy and some a bit cumbersome

The only reason why I did not give it a 10/10 is that it cannot distinguish purchases that came through subscription recharges instead of purchases that were driven directly by email sends. Other than that, the automation qualities, design features, and segmentation options make this an incredible email platform, and I am very happy with it

The system seemed quite slow sometimes. Specifically, there was sometimes a delay in sends if it was during a high traffic period. There were time-outs when uploading new code for an email, and a lag in reporting analytics which was sometimes as long as 72 hours

I think the overall support for Constant Contact has always been incredible; I have nothing negative to say. Our customer support representative was attentive, easy to understand, and very knowledgeable. I never felt like I wasn't a priority of his and my issues, while very small, were fixed in a very short time frame.

Their support is always quick and we have recurring meetings with our advisor. they were great when we first started at walking us through the platform and helping us understand how to do the overall setup. They also have a wide variety of articles that cover must issues in a very clear manner that will get you out of a predicament really fast.

Implementation is very easy for someone who wants to send out the “batch and blast” type newsletters. If you want to use their templates with no customizations, the product works fine. However, the more customizations you get into involving link color, etc, that’s where things can get tricky for someone who may not be familiar with coding

Don't cut corners, do it right the first time, if you take your time to build everything the way you want it then it will run itself. The platform will help you increase revenue as long as you use the tools it provides. Don't be scared to ask questions, the support team will help you get to the next level

Constant Contact
We tried Mailchimp. We could send messages to larger groups for free with Constant Contact. And we simply found more people read the emails and responded more frequently when we used Constant Contact. I think it's because it didn't feel as much like a marketing tool as when we contacted them with Mailchimp.

While Mailchimp was easy to use, Klaviyo allowed much more customization and flexibility. Klaviyo integrated with all of our apps through Shopify, so it was really a no-brainer when it came down to deciding. The ease of setting up a drip campaign and segmenting the customer base was the icing on the cake, but we were already going to go with Klaviyo.

Very reliable in sending email campaigns and controlling the recipients so that no contact is sent the same email more than once, even if they are on a resent list
