Is Instantly Acting Up Lately? Warming + Campaign Issues & No Support Response

Something seems off with Instantly lately — support isn't responding like they used to (it went from resolving issues in minutes or hours a year ago to now getting zero replies). Wondering if anyone else is experiencing similar problems?

Here's what's happening on my end:

Warm-Up Emails Not Sending Normally

Out of 72 warming accounts, about 60 aren’t sending the full 25 warm-up emails per day (excluding premium accounts which are meant to fluctuate).

Just slow, incomplete volume across the board.

I’ve attached old vs. new analytics — new ones show high open rates, likely due to bots.

Campaign Sending is Bugged & Extremely Slow

I started a campaign Monday, targeting 700 contacts

As of now, only 100 emails have gone out in total.

No errors or obvious alerts, just painfully slow delivery.

What I've Tried

Reconnected a number of accounts to reset SMTP settings.

Using a mix of SiteGround and Office 365 senders.

SiteGround accounts show some errors — Instantly seems to be trying to send 10 emails per second, which might be triggering smtp issues.

Thinking of increasing the "wait time per email" from 1 minute to 2–3 minutes to reduce the risk of this.

after 2 Weeks and burned campaigns instantly told me to tick both

-Use a single sending account per time gap

-Send emails one at a time

ive found that ticking first made things worse (snailmail), have tried to untick

Looking for:

Suggestions or workarounds to speed things up.
Anyone with similar issues lately?
Advice on optimal send settings or whether I should consider using an external SMTP relay instead?

Thanks in advance — happy to share insights or test settings to help others as well.
