I see that Florida landlords can now send legal notices to tenants via email, but here’s where I think there’s a catch: I could be wrong, but I think that you still need to have proof that the tenant actually received it. So, if you're switching from traditional mail or that final nail on the coffin to email, I would say that you should make sure you use a method that provides delivery confirmation, like a read receipt or a delivery receipt from your email provider. After all, what’s the point of going digital if you’re left playing hide-and-seek with proof of delivery? And how well will that hold up in court? I think it’s always better to cover your bases, because in property management, a paper trail isn’t just for paperwork. It’s your safety net.

We've always done both. A belt and suspenders if you will:
Registered mail and an email.
Posted notices are seldom needed unless required by CA Law.

Fred Griffin Florida Real Estate 

I do not handle any rentals, so not my cup of tea. It is interesting though!

It depends on the type of eviction, Fred Griffin Florida Real Estate 

I'm not an attorney, yet I work with many who practice in evictions. 

I did prop mgmt. for decades & spent 20 years plus in the courtrooms all over California. 3-day notice, per statute if not served personally is allowed to be posted on the premises & mailed (uspo) to be valid & upheld. Bungle this & you lose your eviction case at trial

US mail or attached to the front door was the norm when I was active. Nice to see that email will now work, but the issue of proof of service still exists. 

I don't really work in the rental market anymore, but when I did the rule of thumb was always to send out these notices in every format... just to make sure that you had all of your bases covered. 

So snail-mail, registered-mail, e-mail, and tape one to their freakin' door.  And make sure to document each and every one (I used to take a photo of the taped notice on their door next to the front page of that day's newspaper... just as proof!).

So crazy but, I never had issues simply texting the notice, Fred. If I didn't receive a response, I would email and certify mail. That happened ONCE and the client was out of the country and didn't have his personal phone on. I hadn't thought to text his business line! 

Depends on the verbiage in the lease which should include what constitutes proper service. AIRCRE forms changed a few years ago to include service by regular mail, certified mail, personal service, *electronic or facsimile transmission*. We had to serve a tenant whose lease was several years old - before electronic transmission was added. Attorney said go ahead and email them but also send them mail if you cannot personally serve them. We emailed, emailed CFO, mailed CA and AZ residences, CA/AZ places of business, Priority, Express, Certified - anticipating that he would feign ignorance. He forgot bragging about the beautiful house he had just built, and didn't think I knew where he lived. That was where the Express went.

We email, and attach to the door.

certified mail or on the door currently

Good question, I think it's a legal one based on what proof of receipt is needed, if for some reason an issue arises. This requirement may vary by state or region. 

I dropped out of the property management business in 2013 Fred Griffin Florida Real Estate . 2010 brought in the oil boom and regretfully the ugly underbelly of drugs and prostitution. I got tired of dealing with meth addicts. I believe they would just ignore emails. I have a friend who is a US Marshall whom I would use... he can't be ignored!

This seems to be a case of a dog chasing their tail.  Nothing happens unless the message is sent and RECEIVED.  Its a hard knock life.  

Here in California it should be posted and attempted to be handed to the tenant.

In CA they need to be mailed and posted on the door in order to constitute service.  Photos of the notice must clearly show the notice, where it's posted, and need to have the date/time stamp showing.  Usually two photos, one of the posted notice up close and one from several feet back showing the notice on the door.  Best if you can also get another with the house and the address in it, but not needed (at least the last time I had to kit up and serve a notice).

While not an attorney, I've served many an eviction notice for my clients.  The perks of being in PM.

Now if you're just changing the terms of tennancy (raising the rent, etc.) then a letter in the mail is all you need.  Email does not count, but that is usually a good way to notify them, especially if they have informed delivery and see the letter coming.  The last time I raised a particular rental was probably five years ago now and I had a text from the tenant all worried when she saw the letter in her informed delivery notice.

And for those saying "five years, what?" I was going to raise them two years ago, but chose not to when the tenant informed me she had cancer.  I've kept her rent steady for two years now to not add to her stress level.
