Alternative to BlunderDelay

I've been using BlunderDelay for years so that my emails automatically go to the Outbox, then send after a certain period. But now BlunderDelay is no longer compatible with the new update (60.3.2 32-bit)! I go through hundreds of emails in a day, so this was essential for me.

I tried using "Send Later", but it's not at all what I want... having to choose a time to be sent manually for each email is a nightmare. And just sending each email without the Outbox is a pain, too, since I have to wait for the progress box to start and finish before I can move on to the next email.

Most of these emails are something that's forwarded to someone else along with a note, so what usually takes 10-15 seconds takes much longer if I have to choose a delay time manually. I just want them to all go to the Outbox, and every 5 minutes or they all just go at once, without interfering with my work.

Can you guys suggest an add-on or trick to make things go like I'm wanting?

Ctrl+Enter (send later) There should also be a down arrow beside the send button they displays a menu with send later on it.

I have the mail merge add-on installed, and I really do not remember if the menu is Thunderbird or the mail merge add-on. So you will perhaps have to decide that for me.

That might be with your add-on... there's no arrow beside of "Send" for me. I can do Ctrl+Shift+Enter to send later, though, or click "File > Send Later".

I tried that last night, but it doesn't send on a fixed schedule or anything. I used it to "send later" an email right before I went to bed, and when I got up it was still in my Outbox. So it's still not at all like I'd had with BlunderDelay, I'll have to manually send on a regular schedule.

I really need an option to just hold them for a short period, then background send so I can keep working.

'Mail Merge' addon puts the arrow next to 'Send' in my Write window.

Composing in offline mode will auto swap the 'Send' button for a 'Send Later' button.


There is an addon called 'Send Later' which has functionality to choose time of sending. https://addons.thunderbird.net/en-US/thunderbird/addon/send-later-3/

I had tried "Send Later" before posting, but it required me to choose a time for each email instead of just sending after X minutes automatically. That takes up more time than just waiting for the progress box to go away! LOL

Unless there's a setting that I overlooked to just automatically send all after a certain period?
