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.

Our email campaigns are simple (we don't require automation) and we don't have a big box CRM. For us, Gammadyne works perfectly. It's simple and cost-effective.

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.

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.

- It would help if the tracking reports didn't expire.
- I would like to see customizing options in the tracking reports.

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.

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

Should be better for UI/UX of the software but Gammadyne work always as expected (That's the most important thing for us)

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.

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

Alternatives Considered
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.

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

Return on Investment
Constant Contact
- Good email marketing option that we need to expand on
- We have not had a strong determinable ROI, but we do not always know if a donation resulted from an email
- Very affordable and we plan in keeping it as a resource
