Failing ❌ in CORE Functionality
I've deep concerns regarding the email delivery issues I have been experiencing with Acumbamail. Despite my efforts and a correct configuration confirmed by Acumbamail, my email campaigns and automation emails are not getting delivered to the recipients (NOT EVEN IN THE SPAM FOLDER).
I have noticed a troubling trend: very poor (almost none) open rates in comparison with my existing service provider, and more alarmingly, I finally observed that emails are not even reaching to the recipients. Over the past few days, I have observed that campaigns sent from the Acumbamail dashboard have NEVER LANDED in the inbox or spam folders.
To illustrate this point, I shared the proof with Acumbamail, my email report, that had NOT RECEIVED campaign emails sent from Acumbamail.
My entire team's contacts are included in the subscriber list, why is it that no one has received the campaign email? Furthermore, I have multiple email addresses included in the subscriber list, and none of them have received the campaign emails either. This is the core function of any email service provider.
My team has conducted a thorough investigation, checking all possible folders—spam, promotions, and even the trash—yet we have not found any trace of the campaign emails.
This lack of visibility into the delivery process is frustrating and leaves us in the dark regarding the status of our communications.
JUST TO RECONFIRM, Last week again, I sent out another email campaign, but once again, it failed to arrive in my inbox, not even landing in the spam folder.
This consistent lack of delivery raises significant concerns about the effectiveness of my email campaigns, automated triggered emails, and the overall reliability of the Acumbamail platform.
The implications of these delivery issues are profound.
I strongly suspect that the reason my email campaigns suffer from low open rates is that they are not reaching the actual email recipients at all.
This leads me to question the underlying mechanics of the email delivery process.
I have already contacted support, but despite waiting over 5 days, I have yet to receive a response.
Are the issues with false reporting, or is there something more systemic occurring in the back-end of Acumbamail?
Understanding the root cause of these delivery failures is crucial for me to regain confidence in the platform and to ensure that my communications reach to out my audience.
Additionally, I have encountered a peculiar issue with the personalization feature in my campaigns. The placeholder *|FIRSTNAME|* has not been populated correctly, and all my test emails are being sent with the name "Neena." This raises further questions about the integrity of the data being used in my campaigns.
I would like to understand why the personalization feature is not functioning as intended. It is imperative that I receive answers to these questions to ensure that my future email campaigns are successful and that I can effectively engage with my audience.
This raises serious concerns about the reliability of the Acumbamail service.
In conclusion, I am seeking clarity and assistance regarding these pressing issues.
I would appreciate a detailed explanation of why my emails are not being delivered to recipients and what steps can be taken to rectify this situation.
I look forward to Acumbamail's prompt response.

Sep 12, 2025Hello,
We sincerely apologize for the inconvenience you’ve experienced with your recent email campaigns.After reviewing your concerns, we’d like to share some key insights that may help clarify the situation:
1. Email Delivery Issues – Likely Causes
The most probable cause of the delivery failures is that your emails are being filtered or bounced by the recipient servers due to list quality issues. If your subscriber list contains outdated, inactive, or unverified email addresses—or if it includes contacts who have not explicitly opted in—this can negatively impact your sender reputation, which in turn can cause emails to be blocked at the server level (not even reaching the spam folder).
To investigate further and provide full transparency, you're welcome to request the delivery log for a specific email. We are fully committed to transparency, and we can provide delivery trace information to confirm that the emails were processed correctly on our end.
2. Personalization Issues (|FIRSTNAME| Tag)
Regarding the |FIRSTNAME| placeholder not populating correctly in test emails: please note that test sends are not linked to any specific subscriber list. Because of this, the system uses a random value from an existing contact record to fill in the placeholder during tests—which explains why the name “Neena” appears in all test emails.
To accurately verify personalization, we recommend sending a real campaign to a test segment that includes your team or your own verified email addresses. This ensures the personalization tags are populated based on actual list data.
We hope this clarifies the situation and provides some direction for the next steps. Once all your concerns are addressed and everything is working as expected, we would greatly appreciate it if you could update your review to reflect your complete experience and the services provided by the platform.
Thank you again for your patience and understanding.
Regards
