Abandoned Cart Recovery Email

This review is done entirely based on my experience, I'm not going to say if it's good or bad, or write a bad review, like, "don't use it, doesn't work" I'd like to be constructive and provide my feedback using this app for more than three years.
It indeed helped to recover abandoned carts using their mail sequence, and the recovery success varies if you have your website in different languages and currencies; if someone had an abandoned cart in French but you sent an email sequence in English, the % of success might be less than if they get a French mail sequence, the same for the currencies, you can define one currency with them, so if you have your Shopify with multiple currencies, then it's getting the problems, the customer is receiving emails with false coins, and the numbers are different as they supposed to be, so few of them just run away. Again, this tool covers just one language and one currency; if you want something sophisticated, it might not work ( or you can use it knowing that, as I did without any problems, I assumed the CR would be lower)
But let's go to the main point; the problem started more than six months ago; a customer sent me an email letting me know that the abandoned cart reminder email went to the spam OK, so I started checking myself, and it was true, I was receiving all their emails to the spam folder, it doesn't matter the address sent, Hotmail, Gmail, Yahoo, always their email went to spam = people can't read them so can't recover any product from my store since they are not receiving them.
After checking the header, I noticed that the IP used by "SendGrid" to send all these recovery emails was flagged from a9ll email serves as SPAM, so everyone using that IP for sending recovery emails went to the SPAM folder; why? Simple they are sending loads and loads of emails have been sent using the same IP/services, and people reported it as spam, and as a result, everyone (using that got flagged ) they told me that it was only me (yeah, I'm the only one using that IP, you are paying me a static IP, yeah, sure) and they manage to change the mail server IP to another/new one, perfect, we tried, it worked, and supposed to be fixed... and they gave me the next six months for "free" just for the inconvenience and for letting them know that their SERVER IP was flagged as SPAM...OK, for BUT yesterday, 6 months after (since this is an automated tool, I completely forgot to check if it was working or not.... I mean, if you configured the app, with a mail sequence, you expect that they are sending) BUT No! any email sent for the last 6 months, 0 , nada nothing, I contacted customer service and after 36 hours I still don't have an answer, and even if they fix the problem tomorrow, they can't help me to recover all these abandoned carts from the last 6 month, they again, claim that everyone is working fine, and they don't know why is not working for me, so 6 months ago I'm kind enough to let them know that their app is flagged as spam, and they thank me without sending any email to anyone, obviously, I stopped using their app, but I keep it for them to test, and check to be able to fix it for the future customers using their app.

After 48 hours, nobody contacted to me, or explain what happened or what is going on, but now from my dashboard ( I deactivated using the app) I saw that a lot of emails had been sent without my permission, or requests, all at the same time, now my customer who left a product on the checkout 6 months ago, is going to receive an email saying " you left something behind...." 6 months after, customer service is getting better and better, and they can't do it worst. Let's see how it ends.

Updated after more than 48 hours:
Thanks for your patience. The technical team has conducted a thorough investigation on your reported case. I want to mention that the reported issue has been fixed, and Emails will now deliver to your Abandoned Carts/Checkouts. We understand your concerns and sincerely apologize for this technical error in your Store's account.

I want to mention that in the past six months Free Trial, all other modules have been working, including the data recording as well as collection and scheduling. The issue occurred only with the email delivery.

So basically, I'm washing my hands, giving you a FREE month, and I'm clapping your back, and this is how this company works in 2023; you might be paying for something that doesn't work.

UPDATE ANSWER: you gave me FREE six months because I was beta testing your product for you and reported emails sent to SPAM folders and IP flagged for SPAM; you claim that "was working", and you gave me six months for FREE the truth is that the app didn't send any email for 6 months when supposed to be working. Now the problem has been solved after 48 hours, why? Because I reported to you if not, you were charging me money for a non-working APP. Did you mention why the APP didn't send any emails for 6 months? What was the problem, and the solution? No, only the problem has been solved; for all future customers, please ADD check if the APP is sending emails correctly; I have better things to do than checking if an automated checkout recovery cart is working correctly and is sending emails correctly, this is YOUR work, and this is why PEOPLE paying for it.

UPDATE 2: since Shopify sends you a reminder of a charging app 48 hours before the charge, and then I contacted this company to let them know about my 6-month problem, they charged me this month because they replied after 48 hours, so I was charged an extra month if you are taking more than 48 hours to reply ( 60 in my case) to re-charge me $12 for this month, you can keep them, now everyone knows how miserable is this company.

Luis was extremely helpful via the chat help even though it was a holiday — 4th of July! He solved my problem and offered to set up all of my email campaigns with my LOGO included, without me asking for it! I'm more encouraged now to purchase their Annual plan instead of the monthly plan. Thank you so much for a great 1st experience with your customer service! Be blessed!

I recently had the pleasure of working with Luis at Abandoned Cart Recovery app for my website, and so far, my experience has been exceptional. The customer support team was extremely helpful in assisting me with the setup process and even went above and beyond by importing 30 days' worth of abandoned carts prior to me adding the app.

I was impressed with how easy the app was to install and set up, and I appreciate the fact that the customer support team was always available to answer any questions or concerns I had.

Although I have not yet had the chance to see the results of the app in action, I am confident that it will help me recover lost sales and increase my revenue. I am looking forward to seeing the impact it will have on my business. The customer service alone is worth the investment, and I am excited to see the positive results this app will bring to my business.
