Send Error campaign

Good afternoon,

Today, I have two campaigns created in a state of "Sent" but the mail did not reach any of the associated contacts list, I send test emails and also reached me, I have a problem with your service?

Hello Mark, 


I took a look at your account and I can see that the last two campaigns are showing as a Sent Status but have no opens.  It looks like for some of the emails they are going to the same domain.  I would suggest, if possible whitelisting Constant Contact to help the email get to the inbox.  You had also spoken with our chat support, and mentioned that if you used a different from email address the emails would be received by your contacts.  The email address you were using as the From email address when it was not delivered could be the issue.  You mentioned that it was a valid email address, but that email address could have been set up to only receive emails, only receive emails internally.  When we send the emails we are sending on behalf of the email address you choose, if it is hitting any internal controls set up for that email address it could be preventing the email from coming through.  


I also noticed that you have previously posted in our Developer Forums about API's.  If you are using an API to schedule the email please post in our developer forums, as they will be able to better assist you.  

I'm still with this problem for mailings and, configured as sender (From)
campaigns do not reach the inboxes customers but if their your Spam

Both directions were tested are not configured to receive only internal emails; was testing from external services


Help please

Hi Mark,


I'm sorry to hear that you are still having trouble receiving the emails to the domain Were you able to follow the instructions that Samantha shared above on how to whitelist our IP addresses so that you can receive our emails? We're showing that the emails are being sent and not bouncing back to us.  Or are you showing that they're going to the Spam folder? I'm not sure I understand your last post.


Let us know, we're happy to help.  For immediate assistance, you can reach our Phone Support at 1-866-289-2101 or 1-781-472-8100.


Thank you in advance!

I'm not receiving the test version emails I've sent to myself, I've send it to different email services and haven't received none

Hi @DavidY174


I'm sorry you're having trouble sending yourself test emails. I understand the importance of sending yourself a test email before you send your email out. I would recommend whitelisting us as a safesender so that you receive test emails. To do this, I would recommend contacting your IT team to help you out with this.

Can you confirm the email was delivered because it has a 0% open? If the email is not getting delivered can you modify it to get through? If not suggest other alternatives or will have to find another way to deliver this email. Thank you, Barbara

Hi @BarbaraL703

I took a look at your email and noticed the 26 people that didn't open the email are from the same domain. Although these didn't bounce it looks like there might be an issue delivering to this domain. Some companies block emails from external parties or only allow specific emails though. Are you in contact with anyone If so, it would be best to ask them to whitelist Constant Contact's sending IP addresses to allow email though. Some other options are you try sending a blank email or an email from your person Yahoo to one of these contacts to see if they are able to get the email at that point.

I have been sending test emails to various email addresses that I have for the past hour and none are sending

HI @SandiJ2

I am sorry to hear this is happening. Can you check your junk or spam folder to make sure it's not there? If not, is it possible for you to try another email address and/or try sending a blank template to yourself to see if there is something being blocked in the content.

I am having the same issue. I have tried several different emails and no one is getting them, also not in their spam folders. One of your guys sent a blank one to one of the email addresses and that worked. I need another way to resolve this.


Hello @MichaelM392. I'm sorry that you are having trouble receiving your test emails! I saw that you were able to receive a blank test email from a member of our Support team when you contacted them yesterday. Have you been able to receive anything since posting here? 


It's possible that one of our IP addresses is being blocked by your security program and that is causing the email to not come through. We recommend whitelisting Constant Contact in your security program which will certainly help with your test emails being delivered! If you have further questions or concerns about the deliverability of your emails, we have a specialized team that will be able to assist you further. Here is a link to their phone numbers and hours of operation.

Please advise as my "Send Test Email" function is not working... thanks!

Hello @MonicaS301


 I took a look at your account and it seems that you reached out to our Delivery team to get help with this issue. If you are still in need of assistance, please let us know. 

Occasional Participant

Yes I am still needing assistance. I called constant contact support yesterday and today and they could not figure it out either, instead they told me to keep testing my email’s content line for line.. Which I’ve been doing all day and still have no solution. I have created 4 or 5 new templates testing out the content that way as well, and still have not reached a conclusion.

Please let me know if you can help me identify my email preventing the test function.

Thank you,

Hi @MonicaS301


Could you please copy the email in question, remove all of the content from it so that it is a blank template, and then try to send the preview to yourself? If you receive that then it indicates that there was something in your email that caused a filter or security setting on your end to block the emails with content from going through. It could be a specific word or the image to word ratio that is causing the issue. I apologize that I cannot tell what might be triggering the filter/security setting since when I send the previews to myself I receive them without a problem. 


If you send a preview of the blank template to yourself and you do not receive it then my next suggestion would be to try whitelisting. Please let us know what happens after trying those steps, thank you!

Can't tell you how many times I have tried sending myself and various other contacts a specific email. I've whitelisted Constant Contact from my firewall and somehow I get all of YOUR advertising emails but none of the tests or newsletters I am sending myself. Knew there was a catch to a 60 day free-trial. Will not be purchasing a subscription unless this is fixed, that's for sure.

Hello @SamanthaL965


Thank you for reaching out to us about this. I did take a look at your account and noticed you specifically sent yourself a live copy of your campaign. Within the reporting of this campaign, I noticed your email address was showing as a Blocked Bounce. This usually means the receiving system would not accept the email. 


You mentioned you have already whitelisted Constant Contact but we do have several sending IP addresses that we use to send from. In order to review this detailed information, you can view our FAQ How to work with ISPs who are blocking your emails to see this information. Were you able to whitelist the range of sending IP addresses?


If you are still finding you are having trouble receiving email campaigns sent directly from Constant Contact, I would suggest calling our Deliverability team. They are experts when it comes to this subject and can certainly offer additional assistance to get this resolved. You can view their hours of operation here


Let us know if you have any additional questions.
