Sent Emails not being received

[Elizabeth36211]

I'm Secretary of a society and send out regular emails to members.  These last few months have been very erratic to say the least, in that some have been received, others going into the spam folder (I know there have been issues) but this month emails have not been received at all by some members, even after having resent them. I have also told everyone to  mark my emails as not spam.

I use TalkTalk webmail and send out 3 emails to myself and BCC to the members, with no more than 28 in each group. This month I received only 1 of the emails ( and I have a talktalk.address), yet all are shown as SENT  in my sent folder.  

This is really not acceptable service, as I need to be confident that my emails are getting through!

I hope that something can be done to improve the situation.

You might also try slightly changing the subject line or adding a small variation to the message, so they’re not seen as duplicates.

Thank you for getting back to us @Elizabeth36211 Please do let us know how things go after trying a longer delay — and if even one member reports the message still not arriving, feel free to update the thread so we can look into alternative options.

Hi Mandisa-TT   To answer your questions - none of the emails bounced back, nor were there any error messages.  There are around 27 recipients in each group and they are being sent out using a mix of providers.  I have told people to place me on their safe sender list but obviously cannot guarantee that that has been done.  I usually leave a small amount of time between sending emails out.  I do however send out an identical email x 3, usually within about 20/25 minutes.  I can try and extend that time and see if that makes a difference.  Thanks for the suggestion.  Hopefully that may solve the issue.

In the meantime, here are a few steps that may help improve deliverability:
> Ask your recipients to add your email address to their Safe Senders / Contacts list.
> Try sending the batches with a small delay in between, rather than all at once.
> If possible, avoid sending identical messages to multiple groups within a short time frame, as this can trigger automated filters.

If you can provide the details requested above, we can investigate further for you and check whether anything on our side may be affecting your sending pattern.

@Elizabeth36211 Thanks for your post, and I’m sorry to hear you’re having trouble with your emails not being received. I understand how important it is for you, especially when sending information to society members, so let’s see what we can do to help.

From what you’ve described, it sounds like the issue may be related to how mail providers are filtering bulk or BCC‑group messages. Even if emails show as “Sent” in Webmail, they can still be delayed, filtered, or rejected by receiving systems.

To help us look into this, could you please confirm the following:
1. Are any bounce‑back or error messages being returned to you?
These are usually key to understanding why a message didn’t reach the recipient.

2. Roughly how many recipients are in each BCC group?
Some providers apply stricter filtering based on bulk‑send patterns.

3. Are members using a mix of providers (e.g., Gmail, Outlook, BT, TalkTalk)?
Delivery can vary depending on the receiving server’s spam checks.
