Hi there @Itamar,
Welcome to the Community! Happy to help!
I definitely understand increased sending around Cyber Weekend. While you can definitely upgrade and downgrade at any time, I think it’s always important to consider the surrounding factors around upgrading to send a larger volume than normal. For instance, what is your sending reputation like for your brand? Do you have a strong deliverability that can handle the increase in volume?
I would recommend investigating your current open rates and ensure these are strong before increasing volume. If you are in good standing with inbox providers, then you should be good for a sudden spike in sending. However, if you are still establishing your sender reputation/warming your account or you open rates are low, a spike in sending volume would negatively impact your deliverability therefore sending lots of your emails to spam and you’ll have to put a lot of effort into repairing your sender reputation so inbox providers trust you again.
Finally, I’d recommend checking out these topics for further insight into this!
Thanks for participating in the Community!
