Litmus from Validity
Chose Litmus from Validity
I have only done a demo with return path. They did have great software for deliverability and overall ESP health. Litmus's rendering functions is more robust that Iterable's, which is why our team decided to keep using it.
Chose Litmus from Validity
From a platform and tool perspective, Litmus does a great job at providing rendering testing. No issues.
Chose Litmus from Validity
We currently use both Everest and Litmus. In my opinion, the way our team uses Litmus would rank in second place compared to Everest. Everest not only reports on deliverability, feedback loops, spam traps, block listings, domain and IP reputation, and so much more, but it also …
Chose Litmus from Validity
Our team has used Return-path in the past, but it seems like the features continue to grow with Litmus, which is very exciting
Chose Litmus from Validity
At my past companies, I've only used Litmus for this use case.
Chose Litmus from Validity
We love Litmus's live previews capability, which is something that ReturnPath did not have at the time our contract started. We do see that Everest does have this feature now, but we do appreciate the direct in-app sync that Litmus offers (so that we don't have to log in to a …
Chose Litmus from Validity
We tested out Return Path, which didn't fit our needs at all, and looked into Email on Acid. EoA didn't meet some of our legal requirements, so we have always been with Litmus and look forward to being a Litmus customer.
Chose Litmus from Validity
Litmus was chosen by my organization. I have used Return Path and Litmus and find Litmus more user friendly.
Chose Litmus from Validity
I have previously used Email on Acid and Salesforce ReturnPath. Litmus is an easy to use product that has a great team behind it. Our team wasn’t comfortable with the new upgrades that Litmus recently installed. The Litmus team was great with setting up a conference call with …
Chose Litmus from Validity
A few years ago when we were researching tools that could help resolve our rendering issues, I came across Litmus and Email on Acid. We discovered that other vendors we used offered rendering testing, but ultimately discovered that they were all licensing the Litmus tool inside …
Chose Litmus from Validity
It's been years since I've used Return Path. Email on Acid is excellent and very comparable to Litmus. We chose Litmus because it seems to be better suited for marketing agencies, and better allows us to create sub-accounts by client or by internal team.
Chose Litmus from Validity
Email on Acid is the other system that I've used that is similar.
Chose Litmus from Validity
We simply use Litmus for the email preview functionality & spam testing. We are using the tool to cut down on our production time and bring visibility to our testing. The software is essentially a proactive tool to help keep our sender reputation high. The competition may offer …

Like I said before, Return Path is really the budget bundle. You get a lot of service for how much you pay. Since I am currently at an early stage startup, we could not afford Litmus, so having Return Path is crucial. The partnership with Salesforce also allowed us to get it at …
Chose Everest (Return Path + 250ok)
Litmus does a great job of checking for specific things related to design or spam filtering, but the overall comprehensive approach that Everest (Return Path + 250ok) has by implementing seed listing, list validation, and pixel engagement offers a much stronger solution for …
Chose Everest (Return Path + 250ok)
Return Path is the most user-friendly and feature rich platform based on the alternatives that we have evaluated or used in the past.
Chose Everest (Return Path + 250ok)
As a long-term Return Path client, we haven't ever used any competitor products as we always felt that what we were using was best-available. So when 250ok and Return Path were combined, the best of both is visible within the new Everest umbrella product, Validity Everest …
Chose Everest (Return Path + 250ok)
Return Path came with our Salesforce Marketing Cloud implementation. We have not seriously looked at additional tools to complement or replace what we're getting through Return Path.

Proofing your emails is necessary. This is a tool that allows you to see how your email not only renders on multiple devices but how it performs. Some email building platforms will tell you their drag and drop templates are ready to go, however they stop short of analyzing accessibility, checking links, load speed among other things. I've also experienced drag and drop template issues as new email clients are released. Litmus provides peace of mind that you did your due diligence on crafting your email. While Litmus does provide some reporting you will not see every typical analytic an email report offers. However, you can use your Litmus data to enhance your email reports which in turn creates a robust view of email performance.

Our early experiences with SparkPost were great; we were looking for a low-cost (or no-cost) solution to our email messaging needs, and SparkPost had the best low-cost option: 100,000 messages per month for free, guaranteed for life. Even though our team has experience with other APIs, we chose SparkPost because it felt like the best value. Our experience with it was great. Two years ago, they discontinued their free option but sent the existing users the following message: "When you signed up, we promised that if we ever changed the terms of our 100K free plan, we would continue to honor the original plan for the life of the account. I would like to reaffirm this promise: while this plan is no longer available to new customers, you are grandfathered into this level of free sending volume." The following year, apparently following a change in leadership, they decided to "deprecate" existing free plans, dropping us down from 100,000 messages per month to 500, the lowest of any email API service I'm aware of. No recognition of the broken promise, the reneged guarantee, just a 20% off coupon. This atrocious behavior that reeks of a new culture of squeezing as much money as possible out of its users and has coincided with a steady deterioration of functionality and customer service. At this point, I have no idea why anyone would pay more for a worse service that treats its users so poorly when you could use SendGrid or a similar competitor for a lower price and way more features.

Pros
Validity
  • We haven’t explored the personalization features in depth yet, aside from using the Add-to-Calendar option, but we're excited to dig in further. Tools like live polls offer an easy way to boost engagement in our product marketing emails, and we see a lot of potential in using these templates to enhance personalization moving forward.
  • Litmus’ continuing education resources have been really helpful. I recently read an article on email deliverability that offered practical insights my team can apply moving forward. I especially appreciate how Litmus uses real examples and stats from the brands they work with—it makes the content feel actionable and relevant.

Cons
Validity
  • I've not seen many limitations but I have noticed that sometimes emails sent from our CRM take too long to land in Litmus, or sometimes don't land at all.
  • As a beginner it was quite difficult for me to make my way around the platform - I thought "Create new" CTA was actually creating something new, maybe "Import from CRM" would have been more understandable. There were a few others but I remember this one.
  • In the Emails section, whenever I hover over an email, I want to be able to copy the subject line instead of getting the different CTAs appear intrusively (Summary, Builder, Previews & QA, Proof, Analytics, Monitor) - maybe these could appear on the bottom of the textbox, instead of them being imposed on top?

  • When I first implemented SparkPost, I did not take advantage of the sub-account feature, and my account was suspended on New Year's Eve. It took two days until I could speak with a support representative to get my account re-activated. I am now using sub-accounts to alleviate the underlying problem, but I was disappointed that my account was suspended by an automated system with no notice.

It's one the best tools that we've found for this type of tool but we would like some additional features like spell check so if there's a platform that features that with everything else Litmus has, then we'd potentially look to move over to that platform instead. However, we are overall pretty help with the platform

We have two separate areas for using Return Path. Our web ecommerce area that is using only transactional emails and a marketing email program that is partnered on the backend with Return Path. I see Return Path continuing to be utilized with our marketing emails, but over time I see less need for our transactional emails to maintain Return Path components.

Litmus has integrations that make the software an integrated part of my work every day. Being able to test right within my email builder is just brilliant. Daily I also use the web interface to review analytics and spam testing. Overall it is one of the pieces of software I use daily without any complaints or issues.

As with all technology, there are inevitably use-cases where you are unable to get to your original goal without some good old-fashioned experimenting. Some situations will (and are) more urgent which complicates an effective integration of a new process or a new team using an existing process but the "issues" are regularly resolved by re-starting the process specific to when Litmus is introduced to a project. If it doesn't come out the way you're anticipating, run it again and verify there is an issue before declaring all is lost

Would give it a zero if I could. Their customer service used to be incredible; fast response times, really hands-on with their users, and a pretty regular feedback process. They sent me an awesome t-shirt that became part of my go-to climbing gear. But for the past year, their response times went way down, their customer service was less helpful and generally a lot more rude, and they haven't asked for customer input once since their leadership change

Absolutely fantastic support. It runs circles around the competition. They regularly reach out and chat, even if it's just to see if there's any issues we need to discuss. They clearly want the business and don't forget you once you sign the contract which is an issue with other similar services.
